mail-notification widget hangs in KDE4 taskbar

[Vik]

Using current updated 8.10 with KDE4 desktop (Heron theme) on AMD Turion dual-screen laptop.

Two IMAP mailboxes being searched, both running OK.

mail-notification running in system tray. Shows "1" on envelope indicating one message pending.

In "preferences", it is set to regard new mail as read if clicked.

Hovering cursor shows the header of the 1 mail message. it is spam and will be auto-removed by Thunderbird in this particular test.

Clicking the mail-notification icon in the system tray does not appear to change it.

Hovering the cursor over the icon now no longer shows the header of any mail message (even if there are new ones).

Right-clicking on the icon no longer brings up the menu.

The mail count on the icon never changes again.

mail-notification 5.4.dfsg.1-1build1
kdebase-workspace-bin 4:4.2.0-0ubuntu1~intrepid1~ppa7

This is still repeatably happening in Jaunty.

Reduced it to just one of the two mailboxes. Still crashes as above under current updated Jaunty system.

Confirmed on Kubuntu 9.10 (Jaunty). The error seems to be only with the panel icon, and only occurs when the program tries to make it disappear. If I always leave a single mail unread in my mail box, no problems at all. As soon as I read the last unread mail, the next time it checks for mail the panel icon becomes unresponsive and still shows 1 unread message (no popups on hover though, clicking does nothing). Later when new mail arrives the panel icon remains unchanged at what it was previously and completely frozen. Starting with no unread mail works fine, as the panel icon is not shown. It is only after the panel icon shows up, that it is then impossible for it to disappear without freezing.

I ran it from the console with --enable-info and it looks like it is still working fine in the background. It checks mail regularly and prints the number of messages found correctly. It is only the panel icon that is frozen.

Confirm on Kubuntu Lucid

This bug also exists on Fedora.
I've created a patch to workaround this problem, but I need to clean it up a bit first. I expect to be able to upload this patch later today

[Daniel Eckl (daniel-eckl)]

That'd be wonderful. I'm standing by to test your patch as soon as it's ready.

[Daniel Eckl (daniel-eckl)]

Just as a sidenote: The problem is caused by the function to hide the tray icon when the counter is 0.
So there is one workaround that is quite hidden: You can let mail-notification show the icon even when the counter is 0.

To do so, install gconf-editor
Go to desktop -> apps -> mail-notification and there check the function "always-display-icon".

The freezes are gone then, but you have to live with an additional icon that eats up tray space even when there is nothing to show.

[Erik van Pienbroek (openftd)]

As promised, here's the patch I've created to work around this problem. What it does is that whenever the number of unread messages is reduced to 0, the icon will be destroyed and recreated. This newly created icon is hidden by default.

[Daniel Eckl (daniel-eckl)]

It builds without warnings (hmm well, I mean there are not more warnings than without the patch *g*) and works really great for me! Thank you very much Erik!

I hope Jean-Yves Lefort has no further objections and can include it :)

[Maarten Bezemer (veger)]

There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates.
Has the patch been included and is the hang indeed fixed with it?
It would help us a lot if you could test it on a currently supported Ubuntu version. When you test it and it is still an issue, kindly upload the updated logs by running apport-collect 330351 and any other logs that are relevant for this particular issue.
