SVN commit 1126274 by mwiesweg:

Fix bug where logic was reverted.
As there is no such thing as a null QSqlQuery, pass only the query text
and the last error to the error handler.

SVN commit 1126275 by mwiesweg:

Fix various bugs with SQL error handling:
For SQLite, there is no sense in trying to close database and reconnect. In
fact, the database
will open again, but remain locked in this case, so that all subsequent
statements fail.
Limit connection error handling to MySQL.
Restructure query error handling, reuse code.

SVN commit 1126276 by mwiesweg:

When a new tag was added by TagsCache, invalidate the internal cache.
When a transaction is active, the TagChangeset may arrive only later;
but we know that the tag was changed.
(this was the original SQL error that caused, though itself no problem,
 a lot of problems due to broken error handling in 235928)
