when i try to run Komodo Edit 8.0 from terminal, it returns me this error:

(process:9508): GLib-CRITICAL **: g_slice_set_config: assertion `sys_page_size == 0' failed

how can i fix this?

note: nevertheless, the application lauches and runs properly.

I believe you can ignore that error, I get that with almost any process that uses the GUI or GLib when I launch it from the command line. That or similar errors. –  Thomas W. Jul 21 '13 at 20:48
As long as the process still runs and works, those are more or less irrelevant bits of data, but don't quote me on that one, I'm not entirely certain –  Thomas W. Sep 2 '13 at 1:39

This is being tracked on the Mozilla bug tracker at


At the moment there is no fix, but the error/warning can be ignored.

For the last week, I have been getting this when starting Thunderbird, which starts slowly but OK and with a diminished window (although I always closeTB on fullscreen)

This is still open on 13.04 (first reported in 2011)
