[Bug 607084] [NEW] Fetching POP3 Mail in KMail sometimes fails

[sven-ola]

Public bug reported:

Binary package hint: kdepimlibs5

With KMail - while fetching mail with POP3 - it sometimes fails,
sometimes I got mail twice, sometimes mails are missing.

Root cause: the /usr/lib/kde4/kio_pop3.so implements an overlapping
buffer shift with memcpy() which has unpredictable results. Needs two
memmove() to fix this, see attached patch. Bug is valid  since ages
AFAICT by looking into the source repo. Anybody _using_ Kmail these
days?

I tried to spread a fix upstream on the kdepim mailing list and added
comment to a couple of kde bugs but no reaction. Either relevant people
are all on holiday or I send to wrong channels. I'd like to have this
fixed, e.g if the next secuirty update overwrites my own version of the
kio_pop3.so file.
