[Qgis-user] Serious bug returns to Qgis revision 13878

[Marco Hugentobler]

Hi William

Ah, good to know it is the icon generation that makes loading projects with 
many raster layers slow. 

Making a user option to disable layer icons sounds good. However, this would 
involve a string change (option dialog). String freeze for 1.5 is already over 
for a while now. So (unless there is a better solution for the problem without 
string change) something for 1.6... 

Regards,
Marco
