Created attachment 49460 [details] The backtrace Version: CVS (using Devel) OS: Linux Using yakuake, it crashes when I close the tabs. It seems that I need to be working for some time on that tab (have the tab open for some time and doing work) before this happens. I always close the tabs with CTRL+D. Trying to reproduce with brand new tabs it doesn't happen. After doing some work (any kind) some tabs properly close but suddenly trying to close one of the others it crashes the whole application. Reproducible: Sometimes Steps to Reproduce: Work for some time on one tab and close it using CTRL+D. Actual Results: It crashes yakuake Expected Results: The tab is just closed. This behavior started after trunk unfreeze (4.5 was tagged and 4.6 cycle started).
