[Fernando Miguel (fernandomiguel)]

manually removing it from accounts.xml fixed it for me.

[Chris Coulson (chrisccoulson)]

Thanks BUGabundo, the crash report looks complete and seems obvious why it crashed. Will send this upstream shortly.

[Chris Coulson (chrisccoulson)]

This crash has been fixed in the latest version of Pidgin by checking that the PurplePlugin object is not NULL before trying to use it. Please feel free to reopen this if you can still recreate the problem with the latest version.

[Yann (yourfrenchman)]

Hi,

I have the problem with the latest version : it does open and closes immediately, so i can't use it anymore.
