I have no good idea on why this is happening. Perhaps one of these pointers 
will provide a useful cue to work with:

1. The symbol "_ZNK7QString11lastIndexOfER7QRegExpi" should be in Qt. More 
precisely in libQtCore.so . You can run something like
	strings /usr/lib/libQtCore.so | grep "lastIndexOf"
to verify it really exists (with that precise name).

Interestingly, here (on Debian), the symbol is 
called "_ZNK7QString11lastIndexOfERK7QRegExpi". That's real close, but note 
the missing "K".

1b. Running
	strings /path/to/rkward.bin | grep "lastIndexOf"
should contain that precise string as well.

2. If you manage to have one version of rkward with that crash and one 
without, running
	ldd /path/to/rkward.bin
on both binaries could possibly show a relevant difference.

3. Assuming something is going wrong inside rkward code, perhaps trashing some 
memory locations in a strange way, it would be helpful to have the precise 
context. Try running
	rkward --debug-level 5
produce the crash and post the last ~20 lines just before the "undefined 
symbol" message. Please do this several times to make sure the context stays 
the same. If it does not, post several versions.

Regards
Thomas
