With QGIS server update to 2.10 call to certain legend images with GetLegendGraphics causes 500 Server Error (polygon symbols seems OK).
It worked normally in 2.8.
This is from QGIS server log file:

Further information: On my WMS-Server (QGIS 2.10, Ubuntu 14.04) only polygon layers' legend graphics are displayed; any GetLegendGraphic request on a line or point layer results in a 500 error.

I also encountered this issue in QGIS Master.
If someone wants to replicate it, you can download the VM described at http://qgep.github.io/docs/vm/index.html and run the following request

I can confirm this bug with Version 2.10.0 on Linux (Debian Jessie AMD64). Apparently there is a segfault when requesting GetLegendGraphics.

I have tested it, and it seems to be an x-server problem (seems some changes in legend rendering now trigger the need for an X-Server).

What does that mean, can with certain configuration this work? Will this be fixed in next release?
thanks,

I compiled Debian packages from yesterdays (2015-10-07) git master, and it seems that the error is gone. But I also had to install 3 more packages to my system (new dependencies): libqca2 libqwt5-qt4 libqca2-plugin-ossl. Maybe this fixed the error?

Probably not. libqca2 and libqca2-plugin-ossl are for the new authentication system - that has been around in master for two weeks tops. And libqwt5-qt4 shold not be now - but even if it was, IIRC it's only used to display histograms and the GPS information widget. So that should be unrelated too and it must be something else.

I also tested and the issue is indeed gone.
