Most of the time when I visit the map24 page, my firefox (compiled from source) crashes, and if I started it in a terminal window, I get an error message as described below. Sometimes everything works fine... Reproducible: Sometimes Steps to Reproduce: 1. Start firefox 2. visit http://www.map24.de/ 3. search for some place or route Actual Results: New SetWindow SetWindow Destroy The program 'Gecko' received an X Window System error. This probably reflects a bug in the program. The error was 'BadShmSeg (invalid shared segment parameter)'. (Details: serial 785 error_code 178 request_code 147 minor_code 2) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) firefox-bin exited with non-zero status (1) Another time, the serial was 86 instead of 785.

As this looks somewhat like the bug described here: https://bugzilla.mozilla.org/show_bug.cgi?id=189573 and this is a flash issue, some additional info about flash. I'm using gplflash, with the following flags: net-www/gplflash-0.4.13 +alsa -debug +oss
Same problem with www-client/mozilla-firefox-bin-1.0.6-r2; it was serial 342 this time.
I recompiled mozilla-firefox and gplflash with USE=debug. I started firefox with --debug and --sync and tried to set a breakpoint on gdk_x_error. I got the same error again, but the debugger did not stop at the breakpoint. So I still have no stack trace.
Most gplflash will not work with current gecko based browsers. I would suggest you remove the plugin and use netscape-flash or wait for gplflash2 to get to a useable state.
