Description Mike Ely 2017-07-10 16:14:16 UTC

I'm trying to work out how to clean out confidential information from an example message while still including one that will cause the bug. In the meantime, the messages all come from our Veeam Backup and Replication server, so if anyone has access to one of those it should be easy enough to reproduce the bug. Just hit "Reply" to any message generated from same.

If anyone has advice on how to submit sufficient data to reproduce this bug while scrubbing confidential info I'm more than willing to do so.

4.4.10 is unmaintain.
Please try to test on last version 5.5.x (we will release 5.6.0 in 1 month)

Regards

OK. I'll have to bug SuSE about this as I'm running the version that comes with their most-current stable distro. Thanks.

Comment 4 Mike Ely 2017-07-10 17:02:51 UTC

I know resolved, but for my upstream-bothering could you please post a link indicating supported KMail versions and dates? I'd appreciate it.
