browser: fix crash when removing favourite items from the directory tree (fixes #8236)


#1 Updated by Daniel Vaz about 6 years ago

I can't replicate in qgis master.

#2 Updated by Jürgen Fischer about 6 years ago

I can't either.

#3 Updated by Salvatore Larosa about 6 years ago

I am able to reproduce it using the right click and
selecting "Add as favourites" and then "Remove favourites" on the same directory.

I also tried it with 1.8 on the same machine and has worked fine.

#4 Updated by Salvatore Larosa about 6 years ago

...and I can confirm the crash even on Windows XP !

#5 Updated by Daniel Vaz about 6 years ago

Sorry, I was not able to reproduce it with these steps (right click -> add as favorite -> remove favorite)

I am using QGis (github) master compiled version.

#6 Updated by Salvatore Larosa about 6 years ago

Very strange, maybe a Qt issue ?

I don't think it is a local problem as I tried on different machine and I always got the crash.

We need other feedbacks !

#7 Updated by Matthias Kuhn about 6 years ago

It runs into a Q_ASSERT in qgsdataitem.cpp:260
If you could adjust the debug output to include messages of level 2, there would be some output just before ("mName = ....") which could help indicating which item is subject to being removed although not present in the tree.

#8 Updated by Salvatore Larosa about 6 years ago

Hi Matthias,
I did set QGIS_BEBUG=2 and I can see the mName var,
but I don't understand as it might helps !

I noticed the crash just occurs when I use the
'Remove favourites' by right clicking on the folder to remove.

#9 Updated by Giovanni Manghi about 6 years ago

We need other feedbacks !

O also get the crash, you must click on "remove favorite" on the actual folder you added as favorite, not in the folder in the "favorites" category.
