Yesterday I got a message that my /home partition was full so I moved a 10 gb folder to a external hdd. now I got the message again so I did the Disc Usage Analyzer, and I found a 50 GB file in /home/.cache/upstart named gnome-session.log.1.

I I could not read the file so I deleted the file now and it immediately starts filling up with this message

(nautilus:2930): GnomeDesktop-WARNING **: Failed to create thumbnail /home/wouter/.cache/thumbnails/large/13b82fd16426ec5a8f99f1aa286de1f1.png.92B5CX: Fatal error in PNG image file: Write Error

I don't really get what is going on here, the file 13b82fd16426ec5a8f99f1aa286de1f1.png does exist, but I don't think I have used it today anywhere.

How do I prevent this log from filling up again?

Just a comment: that filename is actually the md5 hash of the original file. – Frantique Mar 20 '14 at 11:02
I was wondering about the weird name ^^. – Wouter Mar 20 '14 at 11:10

Possible solutions:

Run the following commands to clear your thumbnails cache.

rm -r ~/.thumbnails
killall nautilus

2. Install Samba
If you don't have samba installed, you can try installing it.

sudo apt-get install samba

3. Disable 'file manager' plugin in GEdit
Open Gedit and go to "Edit >Preferences > Plugins" and turn off the File Browser pane.

I think the clearing the thumbnail cache did the job, I'll keep a eye on it but it appears that it stopped adding the error messages. – Wouter Mar 20 '14 at 11:13
