Bug 42636: A bad bridge line might get TBA stuck. A while ago I reworked the relationship between TorSettings and TorProvider. While doing so I was too strict, and a failure to push settings during initialization will stop the initialization itself, which will result in TBA stuck at the splash screen. The problem appears also on desktop (the user will get a prompt that asks to restart Tor, even though it is not perfect, see #21053). However, on desktop the user can go to the settings and deleting the bridges from there (which is not an optimal experience anyway).
