I ran into this on my Q10 running 10.1.0.4285 as well last week, I was messing around with some converted android applications and was making extra "launchers" for the other action entry points. At some point something got hosed and I couldn't delete applications nor install them.
Ended up doing a security wipe and restore from latest backup. Now I know better, I'll do this type of testing against my Dev Alpha A....
Thought I should post this up here though in case someone from RIM is watching and sees that there's a possibility to mess something up. Shouldn't be an issue for the general consumer, once you enable development mode you better have a backup ready to go for the rest of us.
