So these five applications seg-fault when I try to launch them.

missingfaktor@going-merry ~ $ baobab

(baobab:2730): Gtk-CRITICAL **: gtk_css_section_get_file: assertion `section != NULL' failed

(baobab:2730): Gtk-CRITICAL **: gtk_css_section_get_end_position: assertion `section != NULL' failed

(baobab:2730): Gtk-CRITICAL **: gtk_css_section_get_end_line: assertion `section != NULL' failed

(baobab:2730): Gtk-WARNING **: Theme parsing error: <data>:1:0: Unknown value 'GTK_SHADOW_NONE' for enum type 'GtkShadowType'
Segmentation fault
missingfaktor@going-merry ~ $ cheese
Segmentation fault
missingfaktor@going-merry ~ $ google-chrome 
Segmentation fault
missingfaktor@going-merry ~ $ chromium-browser 
Segmentation fault

What could be the possible reasons, and how do I solve the problem? Thanks.

Edit:

Perhaps I should add that prior to getting errors with chrome and chromium, this happened: My /home drive strangely started filling up, and only 4 KB was left. I deleted several GBs of files repeatedly but this kept happening. So I looked for the directory that held up most space and didn't include my data, and it was .cache. so I deleted it entirely and that freed 5 GB of space. Also the filling up of drive stopped.

Still failing after sudo apt-get update and sudo apt-get upgrade? – Andrejs Cainikovs Sep 14 '12 at 6:33
@AndrejsCainikovs, yes. :( – missingfaktor Sep 14 '12 at 6:37
Looks like GTK theme is screwed up. Change your theme back to the original one, and try again. – Andrejs Cainikovs Sep 14 '12 at 6:46

This question should instead be filed as a bug report, thanks! Instructions here. – jokerdino♦ Sep 14 '12 at 6:57

@missingfaktor Does clearing up the .cache prevent the segmentation fault? Either way, you have to file a bug report in order for the developers to fix the software. – jokerdino♦ Sep 14 '12 at 7:18
