This means there was an error (some function returned -1), but the
error message was not set.  Could you capture the backtrace when this
happens?  It's hard to find the exact point, but going function and
checking what returns -1 should do.

It culd be visible from the logs as well, but not without the code
opened in another window to see where we forgot to set the error
