I think this error started to show after a BZR update (not sure, I went to holidays and my brain lost the logs :P). It shows up ONLY at startup, when Eclipse tries to reopen the editors from the last session. If I have multiple editors open, only the first one shows up the error. To clear the error I must close and reopen the editor. If I have no editors open from the last session, the error did not show up. Oh, and yes, if I uninstall bzr-eclipse plugin, all works fine.

Seems to me that Eclipse is trying to create the editor space when BZR resources are still being initialized, and fails to check VSC information. Any thoughts?

Hi,

It's a know issue that bzr-xmloutut <= 0.8.6 will not work with bzr >= 2.1, a fix is available in bzr-xmloutput trunk.

[Dario Ruellan (druellan)]

Thanks for the answer. BTW, I'm having problems updating Eclipse-BZR 1.1.0 here: https://answers.edge.launchpad.net/bzr-eclipse/+question/102325

It worth the trouble, or everything will got fixed after bzr-xmloutput fix and I can still use 1.1.0?

Thanks again.

[Guillermo Gonzalez (verterok)]

Hi,

Yes, using bzr-xmloutout should solve the issue with bzr-2.1, so you should be able to keep using 1.1.0
