R help - Mar 2012 - igraph: decompose.graph: Error: protect(): protection stack overflow

I just got this error:
> library(igraph)
> comp <- decompose.graph(gr)
Error: protect(): protection stack overflow
Error: protect(): protection stack overflow
> 
what can I do?
the digraph is, indeed, large (300,000 vertexes), but there are very
many very small components (which I would rather not discard).

PS. the doc for decompose.graph does not say which mode is the default.

 *** caught segfault ***
address 0xd8, cause 'memory not mapped'

Traceback:
 1: decompose.graph(sc.gr, mode = "strong")
 2: system.time(sc.comp <- decompose.graph(sc.gr, mode = "strong"))

Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace
Selection: 3

What's the difference between Apathy & Ignorance? -I don't know and
don't care!

If you don't get useful help here, you should contact the maintainer of 
the package, who may not be reading your question.  The maintainer is 
listed if you run

library(help=igraph)
