%%%confirmed on osx.
strange, if you set Extrude to 0.164 (inst. 0.163) it renders ok...

%%%btw, is it normal for Textobject -> Convert to Mesh, that generated Mesh has Duplicated Faces?%%%

%%%Confirmed on Linux. Only in BI, works in Cycles.

@sebastian-4
Yes also tried changing Extrude but the error just show up on other frames instead.
I don't get duplicate faces after converting to mesh, but the vertices are not connected (remove doubles cut the vertex count to half).%%%

%%%The problem is scan-fill creates a zero area face (or close enough to zero to cause glitches).%%%

%%%@Campbell, also thought so. Not sure why converting text to mesh solves the issue. Also 2.56 worked fine with this file..%%%

%%%This is something that should work fine always... should check commits in scanfill. It seems as if it's filling the transformed displist now, not the original one.
(remove scale also solves error)%%%

%%%A workaround can be to add a remesh modifier.%%%

%%%I pinned the error down; it was caused by a very bad normal being calculated on a tiny face. The code checks for small faces with FLT_EPSILON, but that value is too small. In other parts of the code we use a 10x larger value of FLT_EPSILON10 instead.

Fix goes to svn now.
