Fetching POP3 Mail in KMail sometimes fails

[sven-ola]

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.
