Bug#33346: Signal 11 crash when viewing source files

Ok, here it is, I hope it helps.

Sorry but my c++ skills are just not up to scratch, however looking at the 
backtrace line #6 both the variables "this" and "filename" have the same 
value.  To me, this looks fishy but I apologise if it's a red herring!

BTW I think kdevelop is a great app but you don't need me to tell you that!

Cheers,
Geoff
