Control: reassign -1 src:cwidget Line 480 in cwidget is indeed and abort(), which raises the exception shown in the stack traces and causes the whole program (aptitude) to, well, abort.
https://source.debian.net/src/cwidget/0.5.16-3/src/cwidget/widgets/menubar.cc Basically, the function tries to hide the menu bar itself or one of its elements (I'm not familiar with the internals of cwidget), with the given reference (w). The loop iterates over the active_menus, but cannot find any that matches for the given reference "w" (in which case it will do the necessary bookkeeping and return from the function). Instead, not finding any matches, ends the loop and finds the abort in the end (which I think that is a bad practice specially in libraries, but well). Given that there are threads and signals involved, I guess that this is a synchronisation issue. I am not sure if aptitude is at fault for misusing sync primitives, but in principle I think that the issue lies more with cwidget, so accordingly I am reassigning it. For the record, I tried to contact Daniel Burrows some weeks/months ago to continue with the development of cwidget, at least to not burden other developers with NMUs when needed and to try to fix problems like these when possible, but no reply from him.
