[solved] mate-panel crashes on startup

[solved] mate-panel crashes on startup

Postby munizao on Mon Jan 21, 2013 8:42 pm

Using Linux Mint 14, 64bit.

Recently I did a fair bit of customization of the MATE panel, adding a second panel and a whole bunch of applets, including an applet that I wrote myself. (For all I know it could be doing something broken, but that doesn't seem to excuse the problems I'm having.)

Now mate-panel doesn't load upon rebooting my system. When I load it manually from a terminal, I get:

(mate-panel:4425): MateComponent-Activation-CRITICAL **: matecomponent_activation_query: assertion `ac != NULL' failed
Segmentation fault

Things I've tried:

rm -r ~/.config/mate

mate-panel --reset

I notice that /apps/panel in mateconf-editor still seems to be populated with information that seems to come from my old setup. So I tried

mateconftool-2 --recursive-unset /apps/panel

But it doesn't appear to have changed anything at all in mateconf-editor, so I dunno.

According to the thread at viewtopic.php?f=206&t=122459 I should try to remove the directory "~/.mateconf/apps/panel". This did not exist when I looked.

Stumped now.

Linux Mint is funded by ads and donations.

Oops. This turned out to be my own stupidity. In the process of working on the panel applet that I'm writing, I had installed a .server file which was evidently malformed. Deleting the file fixed the problem. There is still a legitimate bug here: that shouldn't make the panel crash. But it is not a bug that very many users are going to run into.
