reopen 423141 thanks Hi, the bug recurred again today, and I finally discovered the cause. It is because I have Opera currently viewing a page that contains a ® entity in its <title> attribute. When I switch to this tab, Opera uses it as its window title, and then C-t w causes ratpoison to exit with status 134. I managed to capture the error message as well: "Virtual memory exhausted". If I switch to another tab whose title doesn't contain this character, C-t w works fine.
Perhaps this is a UTF-8 issue that hasn't been fully resolved? I'm not sure what other characters may cause this problem, but I can consistently crash ratpoison this way. Anyway, if you want to reproduce this bug, you can create a simple HTML file and open it in Opera, then hit C-t w. Something like this: <html><head><title>Crash page®</title></head><body></body></html> I'm running in a UTF-8 locale, if that makes a difference. Also, my .ratpoisonrc looks like: set winfmt %n%s%80t set wingravity center set font -misc-fixed-medium-r-normal-*-18-*-*-*-*-*-iso10646-1 I suspect it may be a combination of UTF-8 locale, font, and special character in window title, that triggers this bug in ratpoison. The font referenced in above is from the xfonts-efont-unicode (or xfonts-efont-unicode-ib) package. I also attached valgrind to ratpoison, and here is the output: ==24073== Memcheck, a memory error detector. ==24073== Copyright (C) 2002-2007, and GNU GPL'd, by Julian Seward et al. ==24073== Using

Hope this helps to find the real cause of the bug. Please let me know if you want me to re-run valgrind with different options. I've setup my .xsession so that it runs ratpoison in a loop, displaying a prompt whether to restart ratpoison if it crashes. So I should be able to try out different things more easily without having to interrupt my session.
