I've recently updaed to icedove 17.0.7 which is basically
thunderbird 17.0.7. As you might have guessed i use Debian.

When i try to fetch new mails i get this message: "There is not
enough disk space to download messages..." (The message is in
german though)

According to my df command:

    there is enough space left on my disk to store those mails.
    Does somebody know how to fix this?

However when i disable quotas i am able to fetch mails again.
Also this seems to be a bug in the version 17.0.7. I installed
thunderbird version 17.0.8 from the homepage putting it to
/usr/local/share/alternatives/thunderbird and linked it to
/usr/local/bin/icedove also i linked the ~/.icedove to
~/.thunderbird. when i start thunderbird now with quotas enabled
everything is working fine. So it seems either this is debian
specific bug or there is already a fix out there.

In version 17.0.7 this bug is always reproducable.
I uninstalled 17.0.7 and use the version from the homepage as i
need to work with thunderbird / icedove.

can somebody fix this pleaseI uninstalled 17.0.7 and use the
version from the homepage as i need to work with thunderbird /
icedove.

can somebody fix this please??

disabling quota "solves" the problem while it is not at all a "solution" :-/

same on 17.0.8, 24.6.0-1~deb7u1 (and TB v30.x.x)

icedove 10.0.12-1 is not affected!

it seems there exist a patch for thunderbird:
