Bug#1026809: Xlib: sequence lost (0x10000 > 0x...) in reply type 0x... when running emacs

[Vincent Lefevre]

Package: libx11-6
Version: 2:1.8.3-2
Severity: grave
Justification: renders package unusable

or possible data loss?

After the upgrade to libx11-6 2:1.8.3-2, I get the following errors
when running emacs:

e.g.

Xlib: sequence lost (0x10000 > 0x473) in reply type 0x21!
Xlib: sequence lost (0x10000 > 0x58e) in reply type 0xf!
Xlib: sequence lost (0x10000 > 0x9bb) in reply type 0xf!
Xlib: sequence lost (0x10000 > 0xfb4) in reply type 0xc!
Xlib: sequence lost (0x10000 > 0xfbe) in reply type 0xf!

or

Xlib: sequence lost (0x10000 > 0x450) in reply type 0x1c!
Xlib: sequence lost (0x10000 > 0x45b) in reply type 0x13!
Xlib: sequence lost (0x10000 > 0x473) in reply type 0x21!
Xlib: sequence lost (0x10000 > 0x567) in reply type 0xf!
Xlib: sequence lost (0x10000 > 0xa0d) in reply type 0xf!
Xlib: sequence lost (0x10000 > 0xfb7) in reply type 0xc!
Xlib: sequence lost (0x10000 > 0xfc1) in reply type 0xf!

etc.

This changes each time.

Not sure about the bug severity, but if such errors are output,
this means that they are really serious. Otherwise, the end user
shouldn't be bothered. In any case, this must be fixed before
the next Debian release.

I confirm that this is really serious: it can make emacs exit with
a nonzero exit status (exit status 1).

meh, well the offending commit is found so I'll revert that as well
unless a fix is made upstream soon, and that's unlikely due to holidays
