Created attachment 114929 [details] crash report from drkonqi I had Kontact open with the KMail module enabled, but Akregator was the currently focused module. I wasn't interacting with Kontact at all, in fact I wasn't even behind the PC when the crash happened. At first glance this backtrace looks a lot like the one from the bug I marked as possible duplicate, but I'll leave the final judgement on that to someone more familiar with the code. The system wasn't low on memory, so that wouldn't be a reason for realloc to fail. (drkonqi failed to submit this bug because the backtrace took the comments over 64 kB and bugzilla refused to accept the report; please fix this as it's been a pain for years and is probably causing you to miss out on useful bug reports)
Possible duplicate of bug 387393.
Indeed, same backtrace as bug 387393 *** This bug has been marked as a duplicate of bug 387393 ***
