[BUG]: feedly initial sync and subsequent folder sync causes rssguard to close/crash

[rpushd]

Brief description of the issue

rssguard either closes or crashes (I think the latter, but nothing shows in the Windows event log) when adding a feedly account, or when running a manual feedly folder sync after the initial crash.

How to reproduce the bug?

1. Run rssguard
2. Add feedly account
3. Main rssguard window disappears after a few seconds, and is no longer running (no associated process).
4. You are left with a partially synced feed list. In my case, the last few folders showed up, but feeds within those folders did not.

What was the expected result?

Full sync

What actually happened?

Partial sync + process closed or crashed

Debug log

[....]
time=" 47.680" type="debug" -> database: SQLite connection 'FeedlyServiceRoot' is already active.
time=" 47.681" type="debug" -> database: SQLite database connection 'FeedlyServiceRoot' to file 'C:/Users/user/Downloads/rssguard-4.2.4-1f6d7c0b-win64/data4/database/database.db' seems to be established.
time=" 47.907" type="fatal" -> Cannot store account tree: 'CHECK constraint failed: title != '' Unable to fetch row'.

when switching from embedded sqlite db to a mariadb instance:
time=" 34.607" type="fatal" -> Cannot store account tree: 'CONSTRAINT feeds.title failed for rssguard.feeds QMYSQL: Unable to execute statement'.

Operating system and version

can you export your feedly feeds into OPML file and share here?

Sorry, but I would rather not. I would have to some entries first, and it is a sizable list to go through and sanitize. Is there anything else I can check?

I might grab a copy of the source and run it locally with a debugger attached, but finding the time is currently tricky.

it seems that for some reason, some of your feeds does not have title/caption?

i will try to test with some random opml

[rpushd]

I checked, and yes, one feed appears to not have a name. Looks like it wasn't picked up by feedly on import.

[martinrotter]

can you perhaps create opml with only that one signle feed for me to test?

[rpushd]

The offending feed URL was https://www.france24.com/en/rss
It had a blank name. I renamed it, and this appears to have solved the sync crash.
I'm going to do a fresh start and see if I run into any issues.

[martinrotter]

yyes, i managed to reproduce

[rpushd]

Tried again with a fresh start, and it synced fine again. So it does seem to be related to blank names.

OK, I believe it is now fixed. Will be released soon or you can try devbuild.
