[Marcus Better <marcus@better.se>]

Package: libqt4-sql-sqlite
Version: 4:4.8.6+dfsg-2
Severity: important

quassel no longer starts after upgrading to this version. When starting
it with QT_DEBUG_PLUGINS=1 environment variable, it shows this:



QFactoryLoader::QFactoryLoader() looking at "/usr/lib/x86_64-linux-gnu/qt4/plugins/sqldrivers/libqsqlite.so"
"The file '/usr/lib/x86_64-linux-gnu/qt4/plugins/sqldrivers/libqsqlite.so' is not a valid Qt plugin."
         not a plugin

Selected storage backend is not available: "SQLite"
Could not initialize any storage backend! Exiting...
Currently, Quassel supports SQLite3 and PostgreSQL. You need to build your
Qt library with the sqlite or postgres plugin enabled in order for quasselcore
to work.
