Bug 184529

Version:           1.10.4 (using KDE 4.1.4)
Compiler:          gcc 4.3.2 
OS:                Linux
Installed from:    Compiled From Sources

Kmail seems to be leaking memory every time it checks for new email. I've seen its memory usage leap by 2 MB (never to be released again) in a single check, although usually the leak is slower.

I took a look at kmail with valgrind --leak-check=full, and this is the result of about a 30-45 minute run (smaller leaks skipped):

My locale is (since the above has references to localization): LANG=POSIX, LANGUAGE=fi, LC_*=fi_FI.UTF-8 (except LC_COLLATE and LC_MESSAGES=POSIX). This is with an IMAP server on localhost (dovecot 1.1.4), on AMD64.

KDE is version 4:4.1.4-0ubuntu1~intrepid2, but I've compiled KDEPIM myself from sources (though the same behaviour could be observed with the wrapped packages, also with the standard packages in Ubuntu Intrepid). QT version is also visible above (4.4.3, i.e. standard Ubuntu).
