Crash on searching "Current Project" with no project loaded

Self compiled creator with qt 5. (Which is probably the problem).

Steps to reproduce:
1) Open qtcreator
2) Open the search panel (by clicking on Search Results)
3) Select the filter "Current Project"
4) Type into the search term lineedit and hit "Return"
5) Crash

It looks like the search term linedit is actually correctly disabled, but still allows typing.
