Segfault when reopening a saved project

[skankerror]

Hi.

This happens on linux manjaro (based on archlinux) 64bit.
It's impossible to reopen a project.
I open mapmap, create a new color, new mesh, and save this.
Here's backtrace when trying to reopen :

Hi, I suppose you use the developer version of MapMap. We are working to fix this issue that may caused by the recently reorganisation of the code

[skankerror]

Yes I use developer version.

[carlesgutierrez]

At Mapping::read(const QDomElement& obj) uncommenting the line setPaint(MainWindow::window()->getMappingManager().getPaintById(paintId));, allows to load it. MapMap seems to load ok paints, videoplayers, Mappings, but not Paints with video Input sources ( webcam )

Checking videoInput loader process: Loading the project loader remains in an infinite loop at setPlayState(false) from VideoImpl::unloadMovie().

Ok, with last version I can reopen projects.
