Crash on enabling or disabling any mod

I have an odd issue that I have had for some time now. It's not critical but I thought I should mention it.

Any time I enable or disable any mod and then click "restart", the client crashes instead of restarting.

On reloading the client the relevant mods are correctly enabled/disabled and the game works fine.

Crashlog:
