Version: (using KDE KDE 3.1.1) Installed from: Compiled From Sources Compiler: gcc 3.2.2 OS: Linux My noatun often crashes (SIGSEGV) on exit when I have two or more "other plugins" enabled and am running a skinned interface (e.g. winskin, k-jofol, kaiman). Some combinations of "other plugins" that cause the crash are Young Hickory (YH) with Tag Reader (TR), YH with Keyz, and HTML Playlist Export with TR. (I had trouble reproducing it with YH and HTML Playlist Export.) However, it does not seem to crash if I select "quit" from the YH popup menu (as opposed to closing the open interface window). It also crashes when I try to change from a skinned interface to an arbitrary interface with similar combinations of "other plugins" enabled. It also crashes if I am in the configuration window and I try to change too many of the plugins I have loaded (either interface or "other plugins") at the same time. For example, if I am running k-jofol, HTML Export, and TR, I can disable HTML Export and TR while enabling YH and Keyz and I get the following backtrace: ===================================== [New Thread 16384 (LWP 569)] 0x41c28b79 in __wait4 () at __wait4:-1 in __wait4 #0 0x41c28b79 in __wait4 () at __wait4:-1 #1 0x41ca9414 in __DTOR_END__ () from /lib/libc.so.6 #2 0x4157ccd3 in waitpid (pid=-512, stat_loc=0xfffffe00, options=-512) at wrapsyscall.c:181 #3 0x40c13927 in KCrash::defaultCrashHandler(int) () from /opt/kde-3.1.1/lib/libkdecore.so.4 #4 <signal handler called> #5 0x081d538f in ??
