dovecot - Jun 2010 - Error: dict: Leaked a t_pop() call

I'm running dovecot 1.0.7 on CentOS 5.5, and I've configured it to work 
with PostfixAdmin (http://sourceforge.net/projects/postfixadmin/). 
Everything seems to work great, except for one problem. Any time a user 
logs in, I get errors like the following

Jun 19 02:21:59 ve dovecot: dict: Leaked a t_pop() call in I/O handler (nil)
Jun 19 02:21:59 ve dovecot: dict: Raw backtrace: dict [0x40e85e] -> dict 
[0x40e5cc] -> dict(io_loop_handler_run+0x1c9) [0x411279] -> 
dict(io_loop_run+0x18) [0x4106b8] -> dict(main+0x139) [0x408509] -> 
/lib64/libc.so.6(__libc_start_main+0xf4) [0x2ab19ec13994] -> dict[0x407589]

The only information I could find online was from this mailing list a 
few years back: 
http://copilotco.com/mail-archives/dovecot.2007/msg08975.html

The response seems to be "nobody keeps their quota in MySQL", but the 
setup I'm using is what's recommended by the authors of PostfixAdmin:
http://postfixadmin.svn.sourceforge.net/viewvc/postfixadmin/trunk/DOCUMENTS/DOVECOT.txt?revision=808&view=markup

So, I guess my questions are these:

1) Is this error at all serious? Will it impact performance, or can it 
be safely ignored?

2) If it is something that should be addressed, do you think I would be 
better off trying to patch and recompile the 1.0.7 version, or just 
upgrading to a newer version of Dovecot (keeping in mind that 1.0.7 
seems to be the latest available in CentOS repositories)

Thank you for your time, and your outstanding software.

this version is so old it is essentially unsupported

don't use postfix admin,  corporately we use internal written portal,
privately, for this domain etc I use GRS. 
without problem.

*shakes head*  who cares what version they have, it is outdated, and any
bugs may have been found and fixed  years ago! The same applies to
ancient debian versions as well, in ANY software you have issues with,
it is wise to use their latest current stable before asking them for
help, be it dovecot, apache, postfix, bind... or  whatever :) As
developers hate wasting their time on ancient resolved bugs. sadly
people who decide to only rely upon the ancient distro versions need to
remember they are really  "use at your own risk" packages.

Please download 1.2.12, the current stable release, however read the
release notes because some settings will be incompatible with 1.0.x.
there wont be too many differences but might be some, depending on your
setup.

Postfixadmin rocks... definitely, if it supports everything you need,
absolutely use it!

Thanks for the information. I'm not trying to waste your time, and I 
wasn't really asking for 'help' per se, as much as simply a clear
answer
about whether that error was even worth worrying about. I'm well aware 
that 1.0.7 is a pretty old release, and you don't have much control over 
what the distro maintainers choose to package.

Generally speaking, I think there are advantages (not introducing 
incompatibility with other software, simple dependency resolution, 
automatic security updates, etc.) to sticking with repo versions, unless 
you have a compelling reason to do otherwise. In this case, the bugfixes 
and improvements in quota accuracy are a good reason to
upgrade.

I have moved to 1.2.12 and updated my dovecot-dict-quota.conf file, and 
it seems to be working great.

Thanks again.
