Log
$ alacarte

Traceback (most recent call last):
File "/usr/share/alacarte/Alacarte/ItemEditor.py", line 186, in on_response

Debugging
Add the block of code that would open up the debugger to /usr/share/alacarte/Alacarte/ItemEditor.py.
def get_icon_string(editor, image):
# ===================================
# Debugging codes
try:
filename = editor.icon_file
raise
except:
extype, value, tb = sys.exc_info()
pdb.post_mortem(tb)
# ===================================
if filename is not None:
return try_icon_name(filename)
return image.props.icon_name
Run the program again we find out editor.icon_file is supposed to hold the path of user selected icon, but the attribute will go missing if no icon is selected by user.
-> raise
(Pdb) editor.icon_file
'/home/ng/Pictures/py.svg'
-> filename = editor.icon_file
(Pdb) editor.icon_file
*** AttributeError: 'LauncherEditor' object has no attribute 'icon_file'
Final fix
Use hasattr function to fix it.
def get_icon_string(editor, image):
if hasattr(editor, "icon_file"):
return try_icon_name(editor.icon_file)
return image.props.icon_name
