1400966 - Repairing a newsgroup .msf file marks some topics as partially unread

Status: RESOLVED DUPLICATE of bug 520582

(Thunderbird :: Untriaged, defect)

Description

[Christoph Lipka]

User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:55.0) Gecko/20100101 Firefox/55.0
Build ID: 20170824053622

Steps to reproduce:

I'm subscribed to news://news.povray.org:119/povray.animations. I was experiencing strange undesired effects, so in order to fix those, from the properties dialog I chose the option to repair the .msf file.
At that time, the posts were grouped by topic and sorted by ascending "Eingangsreihenfolge" (order of reception?). All posts were marked as read.


Actual results:

The strange undesired effects were fixed; however, all topics with more than one post are now underlined when collapsed (which to me would imply that they contain unread posts), even though when expanded none of the posts are shown in bold (implying that they are all read).

I had observed this behaviour earlier, but AFAIR could always heal this issue by wildly toying around with some menu items related to expanding/collapsing topics and/or marking items as read/unread. This time that doesn't seem to work.

The only way to heal this, currently, seems to be to click on each and every thread, at which point the thread goes back to sane mode. I'm noticing that this makes some tiny "sun-like" icons in front of the topic name disappear; don't know what those mean, nor whether they're related to the issue.


Expected results:

Either
a) all topics should have remained non-underlined when collapsed (implying that they contain no unread posts), or
b) there should be _some_ simple and quick procedure to make them behave again.

Agreed, it is a pain. You are seeing part bug 520582 and part bug 520582.
