Version:           unspecified (using KDE 4.7.2) 
OS:                Linux

Got this from a community member updating to openSUSE 12.1, with testing kde-runtime packages including your recent 4.7.3+ fixes.
"
trailing is the nepomuk server output, the important bit seems to be

[/usr/bin/nepomukservicestub] "10:33:20 The transaction log file has been
produced by server version '06.01.3126'. The version of this server is
'06.01.3127'. If the transaction log is empty or you do not want to replay it
then delete it and start the server again. Otherwise replay the log using the
server of version '06.01.3126' and make checkpoint and shutdown to ensure that
the log is empty, then delete it and start using new version.
"

does this mean it crashed once on 11.4 and now I can't use it on 12.1 unless I
remove that transaction log? would there be a way to export this message to the
user more easily?



here is the nepomukserveroutput
