[STR New]

How to reproduce:
1. Add a printer
2. Try changing printer's driver (PPD) via web interface to a different
PPD. 

CUPS reports that the printer was updated successfully, but it isn't. 

At the same time, lpadmin -m /path/to/ppd -p printer works OK. 

Tested on a nightly build of Ubuntu Utopic server x64 with prepackaged CUPS
1.7.5, and on a custom build of CUPS 1.7.5 on Ubuntu 12.04 x64. 

Attached log file is from Utopic server, it has two actions recorded: 
One is me changing PPD for test1 via web interface, and then changing it
again via lpadmin. Only the second action worked.
