[trojita] [Bug 399863] segfault when repeatedly sorting
https://bugs.kde.org/show_bug.cgi?id=399863 --- Comment #6 from Walter Lapchynski --- Discovered a new quirk today: the smaller the window size, the more likely the problem is to occur. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=399863 --- Comment #5 from Thomas Lübking --- Smells like you'd have to trigger multiple sorts within one event cycle, possibly due to some scheduled model sanitation at cycle starts/ends? => Try to limit the sorting to once per event cycle (eg. w/ a flag and a scheduled λ to clear it) -- You are receiving this mail because: You are watching all bug changes.

--- Comment #3 from Walter Lapchynski ---
After some further testing that involved increasing the memory allocation on
the VMs I was using, I found that there seems to be some relationship between
the amount of messages required to trigger it and the amount of memory. It's
probably based more on size of messages (or mailbox/folder) rather than
individual numbers of messages from what I can tell.
Anyways, similar backtrace with b94f4307.
Thread 1 "trojita" received signal SIGSEGV, Segmentation fault.
