After thinking a bit more about all that:

I think: why the HECK are we setting at all the Out format? We only read 
molecules in Kalzium, we don't write to them (in kde 4.0) so we could (and 
probably should) only set the In format. Since your crash occurs in 
SetOutFormat, this would also quite possibly fix it!!

So please try this: on line 51 of 
kalzium/compoundviewer/openbabel2wrapper.cpp, please apply this diff:
-       Conv.SetInAndOutFormats( inFormat,inFormat );
+       Conv.SetInFormat(inFormat);

Tell me if that works,
