Android.process.acore has stopped unexpectedly

Same error here.

When i stop synchronizing contacts, everything works fine.

I have a huge number of contacts where the email adress is aperently not correct (export from outlook to gmail did nog work out fine). Email adresses are like this:
/o=***BELGIUM/ou=First Administrative Group/cn=Recipients/cn=JAE

Could this be the reason for this error?

(I'd rather ask before start manually changing about 100 contacts and maybe find out that it does not work).

Thanks!

I also had this issue with the acore process. I went into the task manager and killed an installer app that looked like it was still trying to install something. That seemed to do the trick after a re-boot. No need to factory reset. That would be a last ditch solution.
