Error while saving Simulink model

This is the message error if I try to save a Simulink model (both by using the 'save' menu command and the command line 'save_system' ):

An error occurred during a callback while saving 'myFile.slx'. The previously saved version of this file (if any) has not been

changed.

Caused by:

Width and height must be > 0.

Please note that:

• the error pesists even removing all the callbacks used by the model;
• I already tried the command line: restoredefaultpath.

"the error pesists even removing all the callbacks used by the model". Apparently the callbacks have not been completely removed, because "An error occurred during a callback".

Show as much info as possible related to the error.

I have reported all info related to the error. However, in the last session Matlab closed abruptly and at my restart (using the autosave version of the model) the error disappeared.

run "dbstop if error" in MATLAB Command Window first and then save, see if you can get any lead where the error occured.

Ok . I have issued "dbstop if error" in command window. Now I am waiting for a new error occurrence.
