Package: newsboat
Version: 2.13-1
Severity: normal
Dear Maintainer,
when (accidentally) pressing TAB in the main feed (or article) index
view, the program freezes and the cpu load of the process jumps to
100%.
NOTE: The issue just seem to happen in the feed index and in the
article index views when:
1. read feeds are not shown (either by config or pressing 'l')
2. index view is actually empty (all feeds/articles are read)
When this happens, the only viable solution seems to be killing the
process and - at least on my side - it is reproducible 100% of the
times. I didn't test beyond the keystroke/views/config combinations
reported above.
In case it would be useful, here is what gdb shows at the freeze:
