Use an old (as in: has unresolved symbols) regexpeditor shared lib and 
try opening the Filter Dialog in KMail.

No backtrace, just exiting. Last output when run from gdb:

Ok, no crash. But it shouldn't exit either, since the regexpeditor is 
supposed to not be a requirement.
I'm a layman when it comes to dlopening, but it surely gives an error 
when it cannot resolve some symbol instead of quitting the parent 
application?
