Fatal I0 error 11

Question: Which resource is needed for N+ to work properly with X server?

That would help a lot in finding my solution against these crashes.

related bug: 356574 python crashes running N+ svn

Been getting loads of crashes when i am trying to run N+-svn, all of them pointing towards a problem with x server. I checked all lib's and dep's, got those installed and it just stops working after a minute or 2.

Unable to give any further info because there is no crash reported. If there is a way to reproduce one, please inform me. N+-svn is not compiled.

The program 'nicotine.py' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadDrawable (invalid Pixmap or Window parameter)'.
  (Details: serial 562257 error_code 9 request_code 70 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.)

Fixed it. :)

Running EXT 4 setup and done a fresh install. After install of Grub 2, it offered suggested package "desktop-base" and some other suggested packages after that. I installed these and problem seems to be gone. I did not do this the last time. Must be related, i guess.

the following bug seems to be related, and the workaround mentioned has been working for me till now:
