Insight
The latest security update, DSA-2464-1, for Icedove, Debian's version of the Mozilla Thunderbird mail client, contained a regression: the removal of UTF-7 support resulted in incorrect display of IMAP folder names.
For the stable distribution (squeeze), this problem has been fixed in version 3.0.11-1+squeeze10.
We recommend that you upgrade your icedove packages.
