I've noticed that since at least the last two builds of TextMate, using command + ], the command which raises the indentation level (i. e. the keyboard shortcut for »Shift Right« from the Text menu) actually lowers it (it Shifts Left). If I select the Shift Right item from the Text menu, it works just fine.

Is the LaTeX package to blame here? Or is it a weird bug in TextMate 2? How can I trace the problem?

I am not seeing this behavior, so likely something local.

It seems clear that ⌘] is bound to some other action than Text → Shift Right.

If it is bound to a bundle item you can use Bundles → Select Bundle Item… — switch to key equivalent search (⌘4) and press the key. If an item shows up you can click the small arrow to edit it (or ⌥↩) and then fix the key equivalent and/or disable it.
