Bug ID: 295872 Severity: crash Version: unspecified Priority: NOR Assignee: kdepim-bugs@kde.org Summary: Kmail 4.8.1 crashes when reading email GMail IMAP folder Classification: Unclassified OS: Linux Reporter: stephan.diestelho...@gmail.com Hardware: Ubuntu Packages Status: UNCONFIRMED Component: general Product: kmail2 Application: kmail (4.8.0) KDE Platform Version: 4.8.1 (4.8.1) Qt Version: 4.8.0 Operating System: Linux 3.1.4-030104-generic x86_64 Distribution: Ubuntu 11.10 -- Information about the crash: - What I was doing when the application crashed: I was reading the KDE PIM mailing list in my GMail account, while also compiling KDE PIM from GIT (with make -j4). Mentioning this, since the current behaviour may be a data race triggered by timing caused by excessive system load. Happened pretty reliably when opening the folder in my (large) GMail online IMAP folder. Once I have finished compiling KDE PIM from source, I can also test from there and / or patches. The crash can be reproduced every time. -- Backtrace: Application: KMail (kmail), signal: Segmentation fault __lll_lock_wait_private () at ../nptl/sysdeps/unix/sysv/linux/x86_64/lowlevellock.S:97 in ../nptl/sysdeps/unix/sysv/linux/x86_64/lowlevellock.S [Current thread is 1 (Thread 0x7f40c4e397c0 (LWP 3976))] Thread 5 (Thread 0x7f40a37db700 (LWP 4005)): #0 pthread_cond_wait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S:162 #1 0x00007f40b7255c2c in ??
