[Qgis-developer] Raster on the fly

[John C. Tull]

I am running into problems with some existing project files. Here's a crash dump:

Warning: QgsRasterLayer::setDataProvider: Data provider is invalid.
ERROR 10: Pointer 'hDS' is NULL in 'GDALGetRasterCount'.

QGIS(71351,0x7fff70df5ca0) malloc: *** mmap(size=18446744069414588416) failed (error code=12)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug
Warning: Qt has caught an exception thrown from an event handler. Throwing
exceptions from an event handler is not supported in Qt. You must
reimplement QApplication::notify() and catch all exceptions there.

Abort trap

Cheers,
John
