[Athanasius]

I think this is relatively harmless. As you say the app continues running (something should be catching the raise ServerError in order to report back to the user). The rest of the stack trace splat could be useful for other causes of such. In this case we can tell it was just companion.orerve.net not responding in time, rather than an actual issue in the code.

[A-UNDERSCORE-D]

This still occurring?

I'm using version 4.2.3 in the meantime and couldn't notice it again.
