Failed to move message

[Paulo Matos]

Hi,

I started getting some errors like:
signal(error ("Error 102: failed to move message: cannot read
/ho..."))

in 1.4.15. I was hoping the upgrade to 1.6.1 + mu init + mu index would
solve this but unfortunately it didn't.

Do you have any suggestions on how to debug this issue or what the
problem might be? Maybe I need to debug this inside emacs, but given I
haven't done so before I am unsure how to start the debugger when I get
a backtrace like this.

Any suggestions?

I had this problem for the first time just now, after upgrading to 1.6.1 (actually,  from doing "git clone https://github.com/djcb/mu" a few hours ago) and running mu init, mu index.   mu4e was trying to load the file

1628221636.5334_880.mcba1\,U\=98282\:2\,S which didn't exist. However,  1628221636.5334_880.mcba1\,U\=98282\:2\,RS (note the "R" flag at the end) did exist. Once this happens, you are stuck at "Loading message..." and the only way out appears to be to exit emacs. Re-running "mu index" fixed the problem (at least until the next time a glitch like this occurs).
