Restarted my computer, and noticed that Thunderbird which is set to auto-start did not start. So I clicked on the icon on the taskbar, the box highlighted the icon, the cursor spun around for a minute and then just quit. I tried clicking the icon on my Cairo dock, and going into the start programs folder and clicking there, same thing. I tried to start it with a terminal command and got this error:

(process:3354): GLib-CRITICAL **: g_slice_set_config: assertion `sys_page_size == 0' failed

I tried reinstalling with Synaptic, still no luck. I don't want to uninstall and lose all my settings unless I just have to. So does anyone have any other ideas, before I uninstall?

EDIT New Info; ardvark, I did post on both boards because I don't know if its a TB problem, or a Ubuntu problem. Now the response I got over there lead me to open system monitor and I found that TB was still running in the processes, so I ended the process, still would not start, Then had to do a gksudo nautilus, and delete a lock, and parentlock file inside the TB folder. Tried to start the TB -profilemanager, error said file did not exist. Uninstalled and reinstalled tried to start nothing, tried to start with terminal and got the error

(process:3637): GLib-CRITICAL **: g_slice_set_config: assertion `sys_page_size == 0' failed

Then I noticed that I am still getting my new email msg popups. So it's running somewhere.

vfbsilva First that was the whole error msg (on both of them). I tried to start with the command "sudo thunderbird" error was

(process:4261): GLib-CRITICAL **: g_slice_set_config: assertion `sys_page_size == 0' failed

(thunderbird:4261): IBUS-WARNING **: The owner of /home/robby/.config/ibus/bus is not root!

07:32:15 INFO firetray.Handler isChatProvided=true 

The link you gave me was for FF, and I was unsure how to change the chown command to point to TB. Everyone thanks for the responses.

Take a look here: ubuntuforums.org/showthread.php?t=2142601&page=2 Was that the whole output message? –  vfbsilva Aug 12 '13 at 4:01

Try starting thunderbird from a terminal CTRL+ALT+T, post the message you get in the terminal. –  konrad Aug 12 '13 at 9:38
After a couple of unrelated restarts TB started working again. Don't know why. Thanks for the help. –  Acer DeVille Aug 12 '13 at 13:46
