Comment 1 for bug 135410

Addition:
If I try to fetch mails manually with the above mentioned feature enabled kmail response with LIST Operation could not be completed or similar like this (In German: LIST Operation konnte nicht abgeschlossen werden). Then kmail crashes sometimes (not repeatable). At next start kmail fetch the mail with empty date, sender, subject and within the message body only a string like this one mentioned in bug #135394 is displayed.

This behaviour primarily occurs when I try fetching mail manually. At a fresh startup the mail will be fetched "normally" except that the mail will be deleted (see above).

How can I debug this bug and bug #135394 in a manner which will help you to understand, reconstruct

Again, this issue described here is as well as bug #135394 related to a special pop3 server (for provider name and further information about, please contact me privately). But with yesterdays version and at feisty this does not happen
