Eeschema Appcrash when undoing label name replacement

Eeschema Appcrash-es when I use the "Find and Replace" (CTRL+ALT+F) function on labels and undo it. The application crashes only when the to-be replaced labels are on multiple sheets as far as I know.

I created a Eeschema project file in the attachments as a test. Open the schematic and then follow these steps:
1) Use "Find and Replace" (CTRL+ALT+F) in a multi-hierarchical project (just 2 pages is fine)
2) Input the old label name (Label1)
3) Input the replacement label name e.g. Label2
4) De-select the option "Search the current sheet only"
5) Click "Replace all"
6) Close the window
7) Press Undo (Windows shortkeys CTRL+Z)
8) Crash

If more information is necessary to reproduce the problem please let me know. This crash has not been tested on other Kicad versions than 5.1.4-1.
