[Qgis-user] Python console crashes

[Florian El Ahdab]

Hi the list.

I have a very annoying problem with QGis 1.1.0 Pan. The python console is
unusable: when I try to launch it, it crashed QGis.

I have included the crash message. Maybe some of you already have had this
problem before or can explain how to avoid it.
As some might expect, some plugins crash in the same manner, but I haven't
been able to isolate the exact reason yet. Not been able to use the console
obviously doesn't help ;-)

I am running QGis 1.1.0 Pan on Debian with a 2.6.27.4 kernel on a 32bits
Intel Core 2 Duo CPU
I have Python 2.5.2 (r252:60911, Jan  4 2009, 17:40:26)  [GCC 4.3.2] on
linux2

Thanks a lot.
Florian

The program 'modpython' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 19205 error_code 8 request_code 42 minor_code 0)
  (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.)
