Yes, this has been fixed, but on 4.4.10. *** Bug 281816 has been marked as a duplicate of this bug. *** from bug 281816 I was unsubscribing from a newsgroup in knode as descibed in bug #248256. According to bug #248256, this or a very similar crash has been fixed in kdepim 4.4.10, however I just got it in 4.4.11. Hello! Sorry to be the bearer of bad news, but this project has been unmaintained for many years so I am closing this bug. |
