Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me

Qt Creator will segfault when trying to parse a QML file.
Steps to reproduce:
1) Open Qt Creator
2) Open any QML example that ships with Qt Creator.
3) Attempt to open any QML file in the editor.
Alternatively
1) Open Qt Creator
2) Create new QML project
3) Attempt to open any QML file
Alternatively
1) Open Qt Creator
2) Open any QML project
3) Attempt to add a new blank QML file
4) Qt Creator will segfault as soon as you type brackets
In doing testing, it appears that Qt Creator is loading the file in the editor
properly, but when it attempt to parse the text it crashes. Adding import
statements does not crash the editor, but the moment you type any brackets it
will.
