(gdb) print other
$2 = (const KDevelop::Path &) @0x38: <error reading variable>

This one is almost 100% reproducible.
Open project settings -> cmake -> remove the only build dir -> add new
build dir with same path as previous -> "Apply" -> cmake configuration is
started and while it is still running, the crash occurs.
For this one I haven't found the culprit yet.

Regards,
Maciej
