By default, Bugzilla does not search the list of RESOLVED bugs.
You can force it to do so by putting the upper-case word ALL in front of your search query, e.g.: ALL tdelibs
We recommend searching for bugs this way, as you may discover that your bug has already been resolved and fixed in a later release.

backtrace

Backtrace can vary from system to system and even from build to build.

fix patch

the patch fixes the crash for me.

Generally the crash should appear only when KSim::Plugin::fileName() returns TQString(), but for some reason even if d is not NULL d->name is copied to the stack and the link to the on stack copy is returned. This copy is corrupted by later calls. And leads to SIGSEGV.

The by-value return prevents that.

The patch works for me with Slackware 13.1 32-bit. I'm not a C++ guru therefore Tim or Slavek will have to review and approve before pushing to GIT. :)

Good work!
