UI crashes when entering to the one of the project submodules

[vikulikov]

Describe the bug
Pressing shift + s window with submodules opens. After selecting one of the submodules with enter and waiting for 2-3 seconds UI of gitui closes but the app is seemed to be still working because shell is unresponsive.
I have uncommited changes in the submodules. Maybe the problem is around it.

To Reproduce
Steps to reproduce the behavior:

1. Open gitui in the project with submodules
2. Press Shift + s to open submodules view
3. Select any submodule with enter
4. Wait for 2-3 secs
5. See error

Expected behavior
To not crash

Context:

• macOS 13.1
• gitui 0.22.1
• terminal alacritty 0.11.0 (8dbaa0b)
• rustc 1.66.0 (69f9c33d7 2022-12-12)

Tell me please how I can give you additional context. Because I don't see any errors on crash

[extrawurst]

can you run with logging enabled and share that?

Same behaviour here, Ubuntu 22.04. Stable reproduction:

1. Install latest gitui (0.22.1)

cargo install gitui

2. Checkout repo with submodules (reliebly reproduced with another repository too)

git clone --recurse-submodules https://github.com/opengisch/qfieldsync
cd qfieldsync

3. Run gitui in the repo dir
4. Press shift+s
5. Select submodule libqfieldsync
6. GUI loads fine
7. Wait 1-2 seconds
8. GUI crashes
