Can't change profile pic on Android

hello

Trying to change it results in this error, when I touch the pen. Unfortunately I can't neither copy or screenshot the error. Here is the start of ir

```
Error call to function Exponentimageblabla has been rejected
Cause: java.lang.illegalexception

Thank you :) I love keybase

No source file or test is identified in the report. Start by reproducing the profile-picture change on Android and capture the complete error from the failed pen action; done means the failure is understood and changing the profile picture works without the reported exception.
