Bug#841540: [quodlibet] Exfalso hangs when updating track numbers

[Rob Oosterling]

Figured out a solution/workaround, inspired by this: https://github.com/quodlibet/quodlibet/issues/2030 " The workaround is to right click > "Expand column" on at least one other column in the list." You need to do this only once. After, that, I can save modified track numbers without issues. This bug is fixed in Quodlibet 3.7.1, by the way. Kind regards, Rob
