1. Change this line in script /usr/local/wily/system/python/pkginstall3.py:
self.package_type = self.package_type.split(';', 1)[0]
to
self.package_type = self.package_type.split(',', 1)[0]
2. Re-upload the 3rd image tim-mtp-Linux-el5-x64-10.3.0.15.990015 and the install should then proceed without error.
