Trojita crashed when was minimized, idling in INBOX. Another IMAP client was heavily loading new messages (more 20 000) into same INBOX which had Trojita opened. Trojita crashed with std::bad_alloc when it had allocated more then 2.1 GB. So it looks like a memory leak for a newly received messages when IDLE is active. Here is gdb backtrace: terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc Thread 1 "trojita" received signal SIGABRT, Aborted. __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:51 51 ../sysdeps/unix/sysv/linux/raise.c: Adresár alebo súbor neexistuje.
