[Users] [bug] Claws Crashes When Removing Newsgroup Subscriptions in Modal Dialog List

[Byrl Raze Buckbriar]

Note: I am not going to file a bug report since this is easy to replicate in about 15 seconds with a fresh install of claws-mail. If replication fails, email me directly with instructions for needed debug data.

Platform: Debian Bookworm.
Package: claws-mail/stable-backports,now 4.3.0-1~bpo12+1 amd64
DE: XFCE4

1. In the folder pane, right click on NNTP account and select 'Subscribe to Newsgroup'.

2. In the 'Newsgroup Subscription' popup, find a newsgroup that is subscribed already.

3. Click on the newsgroup name in the popup.

4. Immediate crash of the program with GUI disappearing.

5. This happens EVERY time, on EVERY account, EVERY newsgroup, regardless of server, connection, or online/offline status.

6. This bug does not happen in the claws-mail/stable version. It occurs in the backports version noted above.
