**System Information**
Archlinux
Nvidia 7900GT
**Blender Version**
Broken: Blender 2.69 Release (from arch repos)
**Short description of error**
Upon opening the attached file the boolean modifier on the Cube object (which is differencing with the Sphere.001 object) fails with "cannot execute boolean operation". However, transforming Sphere.001 and cancelling causes the error to disappear.
Also note that this makes moving sphere.001 and then undoing to fail the boolean operation.
**Exact steps for others to reproduce the error**
Based on {F34776}
1. Open attached .blend
2. Note that the difference boolean modifier on Cube says "cannot execute boolean operation"
3. Select sphere.001, transform and cancel (G, Esc)
4. The boolean operation will now work as expected
To prove that this is strange behaviour:
1. Save the blendfile
2. Open the blendfile again
3. The boolean is again saying "cannot execute boolean operation"
