From Bugzilla Helper: User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.4.2-2 i686) Description of problem: MATLAB 5.3 (SR_11) startup aborts with (MATLAB) floating point exception unless user is root. ***OK under Gnome*** How reproducible: Always Steps to Reproduce: 1.From KDE desktop -- Open konsole window (or xterm...) 2. *As ordinary user* type: matlab 3. Actual Results: Matlab starts (opening comments + splash screen) then aborts with: ------------------------------------------------------------------------ Floating point exception detected at Wed Jul 4 18:42:24 2001 ------------------------------------------------------------------------ Configuration: MATLAB Version: 5.3.0.14912a (R11) Operating System: Linux 2.4.2-2 #1 Sun Apr 8 20:41:30 EDT 2001 i686 Window System: The XFree86 Project, Inc (4003), display :0.0 Current Visual: 0x21 (class 4, depth 24) --------- [8 MBcore dumped] Expected Results: Matlab Additional info: Matlab launches OK if I su root, but I haven't tried using it much that way (won't). Since this machine/installation of MATLAB works fine under Gnome desktop it looks like a KDE problem. Will also copy The Mathworks.

Matlab must be doing something odd then - guess they're making some assumptions about the root window which don't match what kdesktop/kwin provide. Since we don't have their source (not even the binaries actually), there is little we can do to find a workaround.
