After some research I come to the conclusion that the culprit is the use
of unsigned int for the Glb::ustring::iterators.
replace all used unsigned int in function TrimLabel() with size_t
instead the patch above should do the trick.
Unfortunately I haven´t access to a 64bit machine, so again cant test
it, . . .

Yes, that points me to our TrimLabel() function line 293

would be great if someone could check if that helps on a 64bit arch?

Hi Jeremy
Thanks for the backtrace, unfortunately it isn't really meaningful, so
I have installed ubuntu 12.04 on my box and build guitarix 0.23.1 on
it. well, I cant reproduce the crash here, only conclusion that leaved
over for me is that it is related to x86_64 because I have only i386.
I will try to get access to a 64bit box to debug it, . . :-S
