I'm getting crashes in BuildCraft Beta 5.0.1 when it tries to render facades of BoP blocks. Not been able to trace the cause to a particular block.

From memory it's a NPE in fetching a texture.
Doesn't occur with blocks from vanilla or other mods.
Could do with someone else reproducing the error.

Best to not open this until you have a crash report, otherwise it encourages bad habits.

Also, BuildCraft 5.0.2 sounds like it addressed this
