Setting any band to "Not set" on a multi-band raster crashes qgis

[gsherman]

The summary says it all. Set any band to not set and click Apply or Ok. QGIS crashes.

This also happens in 0.9 and the raster transparency branch.

[timlinux]

Moved to milestone 0.8.2 since we wont be fixing any further issues before the 0.8.1 release

[tutey@…]

I confirm this bug with 0.8.1 SVN 6800. Please find a smallish example 3-band GeoTIFF attached. No chances the bug will be fixed for 0.8.1?

1. qgis merge2.tif

2. double click the layer

3. Symbology->Red->Not Set->OK

Crash. Setting any other band to Not Set crahes QGIS as well. The backtrace is below. merge2.tif is attached.

Program received signal SIGABRT, Aborted.
