Please describe the problem:
While i was compiling stuff, i got a call and was updating an apointment i had
in the evolution calendar.

The compilation caused my /home to be full, and as thus, evolution was unable
to update the apointment.

But instead of opening a dialog informing me about the issue, and let me free
some space, it created a dialog storm, which left the box fully frozen (it was
a 1Ghz powerbook, with 512MB of ram), leaving me unable to move away from
evolution, unable to switch to a VT console, unable to even kill X with the
ctr-alt-del combo (well, maybe due to apple thinking there is no need for both
backspace and del, not sure), leaving me no choice but to reboot the machine.

This caused the loss of all the not-yet-saved data, thus the severity.

Steps to reproduce:
1. Make sure disk is almost full, for example by mounting user test's home directory with mount -t tmpfs -o size=1000000 tmpfs /home/test before logging in
2. Create calendar entries until disk is full


Actual results:
Lots of error messages flood the screen. The only way to regain control of the desktop is to kill the evolution process. Unsaved changes are lost.

Expected results:
Only one error message was shown. Allowed to make more space before saving again.

Does this happen every time?
Yes
