Subject: [PATCH] Fix segmentation fault
|
|
|
|
As reported by Maxim Zhukov, the commit 9ca7710 ("Fix memory leak in
|
|
main view (#931)", 01-06-2019) causes a SIGSEGV when holding the key
|
|
'Stage/Unstage current line' in stage view.
|
|
|
|
Add a check to avoid null pointer dereference.
|
|
|
|
Fixes #971
