Comment 1 Niko Sams 2012-01-22 17:01:51 UTC 
I get the same crash...
Comment 2 Milian Wolff 2012-01-23 08:54:28 UTC 
yup, "known" - isn't there another report for this? anyhow this should be fixed by not using QtConcurrent (which is not a good idea to begin with btw), but instead QThread-based solution or similar that allows user-cancellation. Then inside the cleanup method of the cmakemanager plugin make sure all imports are cancelled and only then return?
