The prior two traces were when I locked up Evince with Ctrl minus and Ctrl plus.
This one is done with trackpad pinch to zoom. It has a thread exit in it too, maybe that's something. These are the remaining threads: (gdb) info thread Id Target Id Frame 6 Thread 0x7fe7c0fa3700 (LWP 4508) "evince" pthread_cond_wait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S:162 5 Thread 0x7fe7c17a4700 (LWP 4507) "evince" 0x00007fe7d5311773 in __GI___poll (fds=<optimized out>, nfds=<optimized out>, timeout=<optimized out>) at ../sysdeps/unix/sysv/linux/poll.c:87 4 Thread 0x7fe7c77fe700 (LWP 4506) "evince" pthread_cond_timedwait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_timedwait.S:216 2 Thread 0x7fe7ccfdd700 (LWP 4504) "evince" 0x00007fe7d5311773 in __GI___poll (fds=<optimized out>, nfds=<optimized out>, timeout=<optimized out>) at ../sysdeps/unix/sysv/linux/poll.c:87 * 1 Thread 0x7fe7d8a0d9a0 (LWP 4503) "evince" 0x00007fe7d5311773 in __GI___poll (fds=<optimized out>, nfds=<optimized out>, timeout=<optimized out>) at ../sysdeps/unix/sysv/linux/poll.c:87 (gdb) ** Attachment added: "gdb backtrace of crash #3 - using pinch gesture" https://bugs.launchpad.net/ubuntu/+source/evince/+bug/875359/+attachment/2548864/+files/backtrace3.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/875359 Title: evince locks up when zooming in or out To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/evince/+bug/875359/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
