Can you attach the structure which provokes this segfault, please, if you haven't already.

ok, i have tried to reproduce the crash and it worked like this:
started the program out of the kde menu.
i used the function: "Im Internet Finden" (i am using the german version, so it may be translated best with: online search structures)
searched for "Acetylcholin" and the only result i got was a structure with the CAS 66-23-9
without selecting the line in the result field i clicked on the button "Auswählen" (Select) and so the pogram chrashes without a hint.

xdrawchem.patch Edit (448 bytes, text/plain)

I can confirm this bug. It only happens if you do not choose one of the items from the list of returned structures.

I recompiled from source to get the debugging information and found the offending line. The program wasn't checking to see if the user had chosen an item before using it.

Please find attached a patch that stops the crash. This bug doesn't seem to have been reported or fixed upstream.

Changed in xdrawchem:
status:	Unconfirmed → Confirmed

Thanks for the patch, fixed in Debian upload xdrawchem_1.9.9-4, to be synced to Ubuntu later.

Unfortunately, this is one of the many ways you can crash xdrawchem, it doesn't cope well with unexpected user input. And it seems upstream is mostly dormant.
