On Wheezy desktop which has had icedove for a while with some history...

If you edit a mail filter rule, and then select it (such as to "Run Now") the highlighting is different
on my GNOME classic desktop, than if the rule has not been editted.

To reproduce:

Open "Tools">"Message Filter".
Click a rule to edit it.
Add (or Delete) a space character to end of rule name (or any other change, but this is non-destructive).
Click "OK".

If the problem has occurred the rule will now be outlined not highlighted in the list of rules.

In normal use the rule is highlighted in light blue, dark blue when editting, and light blue when finished.
Colours may depend on themes.

In my testing this only occurs from rule 17 onwards.

It is 100% reproducible so far (always fatal to promise).

Moving rule 17 to rule 16 (using "Move Up") removed the issue for that rule, but creates the same issue for the filter now in 17th place.

Once the problem has occurred, then highlighting the problem rule will get an outline, but surrounding rules highlight as expected.

I assume some issue with underlying widget structure, or possibly the graphical environment, so if you have trouble reproducing ask.

Hello Simon,

do you have any other desktop environment installed?
If yes can you check if this issue also happen if you use any other X11
environment then Gnome Classic?
Maybe this error is only happen be using the Gnome Desktop.

I don't use more then six or seven filtering rules so I can't test this
quickly.

Hello Simon,

please use "reply all" to keep the BTS updated as well. ;)

O.k. You have that error on TWN too, it seems that this issue is not
X-Window system related.

If anyone else can report something helpful, that would be appreciated.

Regards
Carsten
