Hello Andreas,

to convince QGIS server to log is black magic... if you are working from
the command line, you should set the env vars by exporting them or directly
in the command, this works for me from the cmd line:


QGIS_SERVER_LOG_LEVEL=0 QGIS_SERVER_LOG_FILE=/tmp/qgis-000.log
./qgis_mapserv.fcgi

The ECW/JP2 are probably unrelated to your crash.
