Description Garry Williams 2014-11-20 05:31:23 UTC
Occasionally focus is changed to another (seemingly random) message spontaneously.  It seems to happen when the IMAP (Gmail) server is refreshing.  I believe that focus always lands on an already-read message.

This is very irritating since I now need to find the message I was reading before to resume.

This bug is fairly old, probably since KDE 4 originally shipped in Fedora.

Reproducible: Sometimes

Steps to Reproduce:
1. Read mail
2. Wait for refresh
3. Repeat

It doesn't always happen on a refresh.  I have no idea what the triggering conditions are.  :-(

Actual Results:  
Message list focus jumps to another message.

Expected Results:  
Leave focus on the message I'm reading until I change it.

Maybe automatic expiration (moving message to local folder) is also triggering event, but not sure.  I have many folders in Gmail set to expire message older than a few months by moving them to a local folder.  For example, my foo folder messages migrate over time to my foo-old local folder.

I opened bug 341292 recently and didn't see this one. 
It sounds connected.

This irritating bug persist to this day with kmail2 5.3.0 (Fedora rpm kmail-16.08.2-1.fc24.x86_64).

Still happens usually after a mail check is done on the interval I specified.  Very irritating to be reading a message and have another message jumped to out of the blue.

    $ kmail --version
    kmail2 5.4.3

I'm experiencing this problem also on Arch Linux (kmail 19.12.1), on the contrary, on Fedora 30, with 19.04.2 it works perfectly.

I don't think the version is important in this case. There's something that goes wrong while using kmail (after some time using it, I mean).

I've as well Gmail, but also other mail account providers.

Ín the next days I'll try to clean up the profile folders, in the mean while, can you guys let me know if and how I can debug this? 

One thing I've found is that I can reproduce this bug (only on Arch at the moment) switching between kmail and other windows or even changing workspace.

The highlighted email is always one older than a specific date/time, if I move or delete that email, the focused/highlighted email is the next one.

So there's probably something wrong in the email index (?????). Or some corruption happened starting from a specific date.

I don't know if I'm saying bs regarding the index :-P ... It's just guessing.

Let me know how can I debug this and I'll share more details with pleasure.
