For any comic that has a larger image on a particular day, typically Sunday, when accessed in the comic plasmoid the rotating arrow appears for a few seconds and then the screen goes blank. I am only able to recover by doing ctrl-alt-delete and selecting logoff. Examples of this are "Calvin and Hobbs", "Doonesbury" and Dilbert. This occurs when accessing the Sunday comic by scrolling back using the left-arrow button from a weekday, e.g., Tuesday. Note also, if comic plasmoid is started (i.e., kde started) on a Sunday, the the current (larger) strip simply does not appear when it is of a larger size. No crash occurs. Reproducible: Always Steps to Reproduce: 1. Setup comic with at least one strip like Dilbert 2. Access a smaller weekday strip which appears OK 3. Scroll back to Sunday strip. Actual Results: While attempting to access and display the larger Sunday strip, KDE crashes, i.e., screen goes black. It does responds to crtl-alt-delete so can log out and restart KDE. Expected Results: Larger Sunday strip should appear and KDE should continue running This may have worked OK when Fedora 22 originally installed, not sure. It may require a build-up of cached strips, but I doubt it. Note also, I have KDE4 running on another installation of Fedora 21 and it DOES NOT have this problem and is running the exact same comic code files (main.es) for each strip. Since this completely crashes KDE, I would classify this as "Critical" since data could potentially be lost.
needs a backtrace of plasmashell with debug packages installed
Ok, installed fedora debuginfo packages. After normally started plasmashell killed in konsole, from konsole window ran: $ gdb plasmashell (gdb) run # Desktop and comic plasmoid appears. In comic plasmoid for Calvin and Hobbs, moved from Saturday back to Sunday using the left arrow. Desktop crashes as usual. Konsole window with gdb running still present. (gdb) set pagination off (gdb) set logging on (gdb) thread apply all bt full : : # backtrace dumped to file gdb.txt. There are 11 threads. Thread 1 appears to have been in an infinite recursive loop since it dumped over 11000 levels before I got tired of waiting and killed gdb. The file I attached is gdb.txt cut off at 1000 call levels which shows the repeating pattern. Hopefully, this provides the info you need. Let me know if anything else is required.
Created attachment 95508 [details] gdb.txt truncated at 1000 call levels for thread 1.
After fedora 22 updates (many are kf5-* updates) that I installed today this comic plasmoid problem seems to be fixed! Sunday, larger sized comics display and no KDE shell crash occurs.
