Description Ambroz Bizjak 2016-08-25 22:35:31 UTC
When loading my project [1] in KDevelop 5.0 for the first time, KDevelop freezes. Backtrace indicates a locking issue in the QML/Javascript parser.

[1] https://github.com/ambrop72/aprinter

Reproducible: Always

Steps to Reproduce:
1. If you loaded this project before, clean up the kdevuchain cache.
2. Load the project, any project manager will probably be fine.
3. Application hangs shortly.
