Version: (using KDE 3.5.9) OS: Linux Installed from: Fedora RPMs KMail crashes before the GUI is started when the disk quota is exceeded. There is no information about the reason for the crash (fseek seems to be involved somewhere), and nothing that suggests to the user that it is a quota problem! To reproduce: on a quota controlled system, exceed your quota (generate large file....), and then try to use kmail. kmail does come back without problem once the filesystem is back in quota (deleted large file). I would expect KMail to gracefull inform me that quota is full, hence a write fail. "Please clear out your filesystem!" There are other reports similar to this, however these are reported as 'closed'/'resolved', but this does not seem to be the case!
I do not have a quota controlled system,but I've totally filled the $HOME directory so 0 bytes abailable remains. Then started kmail 1.10.90 (svn trunk r886196), and it works (no crash).
It seems it cannot be reproduced with KDE 4. Please reopen this bug report if you experience this issue again with KDE > 4.2.1.
