[Qgis-developer] QGIS-Server Coredump printing with lizmap webclient

[Roy]

Dear all,

i'm testing qgis-server 2.6.0 with "lizmap web client" on ubuntu 12.04 
server
and qgis server crashes trying to print a vector layer with "advanced 
symbols"
( "line pattern fil"l and "marker line"); apache log following:

# apache2 error.log ########
#mod_fcgid: error reading data, FastCGI server closed connection
#[Mon Nov 10 11:28:47 2014] [error] [client 127.0.0.1] Premature end of 
script headers: qgis_mapserv.fcgi
#[Mon Nov 10 11:28:51 2014] [error] mod_fcgid: process 
/usr/lib/cgi-bin/qgis_mapserv.fcgi(1998) exit(communication error), get 
signal #11, possible coredump generated
# apache2 error.log END ########

using more simple (simple fill) symbology this does not appens

is this possibly a bug or are we not supposed to use "fancy" symbols 
printig with qgis-server ...

thanks,

Roy.

P.S.  is this the right list to ask questions about lizmap and qgis-server?
