[Bug 1012858]

[Nl0]

(In reply to Wayne Mery (:wsmwk) from comment #21)
> David, thanks for reporting your results.  Can you retest please and tell us if this reproduces with a curent beta?

Wayne, as I wrote several times over several years at several places in this bug tracker:
The problem is easily reproducible, also on Linux, with any TB version (meanwhile including 78.4.2.).
Why is there apparently not a single TB developer trying this himself?

Again: just enter an IP address such as 1.2.3.4 as the server name/address.
Then try fetching emails. Until this timeouts,
the progress bar moves forth and back with significant CPU load (10% of one core on my current Linux machine).
