This problem seems to be caused by the package not emptying the contents of /var/cache/tt-rss after an upgrade.
The TT-RSS installation instructions specifically warn users not to reuse cache files between version upgrade as this can often cause problems. Please fix this package so that between upgrades, /var/cache/tt-rss is properly emptied of cache files, keeping only the directory structure. In the mean time, users who encounter javascript errors messages in TT-RSS after upgrading this package may use this command as a temporary workaround : sudo find /var/cache/tt-rss -type f -delete -- Jerome -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
