Bug Description
On Intel Macs, the telescope control feature sends RA=0 for objects that have RA between 12 and 24. The problem is avoided by running Stellarium through Rosetta, which forces the use of the PPC executable in the universal binary.

The issue appears to be caused by differences in handling floating point arithmetic between Windows/Linux/PPC Macs and Intel Macs (and by the smart-but- error-prone way the code converted negative RA values to integer values).
David Hulse identified the code that causes the problem and proposed a solution. It has been committed to Stellarium's code repository at SourceForge as revision 6025: stellarium. svn.sourceforge .net/viewvc/ stellarium? view=rev& revision= 6025
