| Sentry Crash Report: | |||
Notice that there are two backtraces in my report. One of a deadlock or something like that and one crash resulting from this. Same can be confirmed when just switching from one sqlite database to another. After a restart, most of the time the new database has been loaded though. I confirm this dysfunction here too... Gilles Caulier I also confirm this when running the albummodel unit test Switching between SQLite databases works for me now. Is this bug still valid? Will check this later. Can't reproduce this now. |
Version: trunk (using KDE 4.4.2) Installed from: Archlinux Packages Digikam was set to mysql but the settings were wrong from a test run, so no actual connection to a mysql server was existing. Then I changed the settings back to my sqlite database. Pressing ok never returned. This is the backtrace of an attached gdb: (gdb) thread apply all bt Thread 16 (Thread 0x7f6ac7e77710 (LWP 6549)): #0 0x00007f6ad759b10c in pthread_cond_wait@@GLIBC_2.3.2 () from /lib/libpthread.so.0 #1 0x00007f6ad781e8a3 in ??
