From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-GB; rv:1.7.12) Gecko/20050922 Fedora/1.0.7-1.1.fc4 Firefox/1.0.7 Description of problem: When printing from Mathematica 5.0, Metacity crashed immediately after the Print dialog box disappeared. The crashing was repeatable within that Mathematica session, but subsequent sessions did not produce the fault. (This has been observed with other applications as well, but I cannot remember where.) BlueCurve theme was active at the time. Version-Release number of selected component (if applicable): metacity-2.10.3-1 How reproducible: Sometimes Steps to Reproduce: 1. Print a Mathematica notebook (either to file or lpr). Actual Results: Metacity segfaults. Expected Results: No crash. Additional info: I've obtained a core dump of Metacity for further study. Anyone interested, let me know and I'll post it (it's ~2.5 Mb).
