Hello,
when I try to convert from mbox to mdbox with dsync with one user it
always panics:

But it's difficult to guess where it's allocating that. I'd need a gdb backtrace. Does it write a core file to userxy's home dir? If not, try replacing dsync with a script that runs "ulimit -c unlimited" first and then execs dsync. http://dovecot.org/bugreport.html tells what to do with core once you have it. Alternative idea: Does it crash also when dsyncing locally? gdb --args dsync -u userxy backup mdbox:/tmp/foobar run bt full
