Unable to change schedule column width

[tetrahedon7]

After changing the schedule column width in tudurc, when I open tudu, it sort of opens and then closes again. Then when try opening it again it gives me the warning

Lock file found

either
    Another program may be editing the same file.
    If this is the case, be careful not to end up with two
    different instances of the same file when making changes.
    Quit, or continue with caution.

or
    A tudu session for this file crashed.
    "Edit anyway" will destroy the lock file.

[E]dit anyway, [Q]uit:

This happens everytime I try to open tudu with the changed schedule column width. I can still open it, ofc, but having to go through this everytime i want to access my tasks takes away a little of the functionality of tudu for me. Is there a fix to this?

####Steps to reporoduce
Change the line row = 70%(tree,vpipe,30|schedule) # Show the schedule on the right side of screen to any other value "__|schedule".

Strangely enough, the same issue doesn't recur when changing the line above this one,
row = 1(blank,vpipe,50|blank)

Also, this only happens when I open tudu maximised. When I open it in a minimised window which the changed tudurc, it opens normally, but doesn't show the schedule panel at all. Maximising the window then shows error "Segmentation fault (core dumped)",
