[Qgis-developer] qgis-server will crash on a specific project

[Andrea Peri]

Hi,

I do some other tests.

I take my project that give QG crash and split it in two compementary projects.
Of course I do this using qgis desktop to avoid unvolontary errors.

Testing both of them on QS there is no crash !

So:
The first plausible theory I can give is that Qgis-Server has a LIMIT
to the number of Groups or Layers it can have in a project.
A limit different (and less) than qgis desktop (osgeo4w version).

Is this a plausible theory ?

Thx,

Andrea.
