Same here. Filename become truncated in other GtkImages ("test.png" -> "tes.png").

Same problem here, after changing a single GtkImage filename, the filename transfers to all GtkImages. Also the relative path disappears from all GtkImages.

Arch Linux, Glade 3.20.0

I have thus problem since november 2015 :

I tripped over this problem tonight with glade 3.20.0.
I've been working around it by constantly hand-editing the xml file.

In my experience, this appears to be the behaviour when trying to select image files that are contained within a subfolder where the .glade file is saved.

Having all the relevant image files in the same folder as the .glade file appears to be fine and Glade does not have this issue. This of course means that the folder gets very cluttered.

Still present as of 3.20.2.

This is not specific to subfolders of the .glade file's folder, it also happens with images in folders outside the .glade file's folder entirely.

I can confirm that putting the images in the same folder as the .glade file doesn't trigger this bug.

thanks for the report guys!

fixed in master and 3.20
