Comment (by starlight):

 This bug _might_ be reproducible.

 It depends on accessing a particular site
 with a somewhat uncommon client configuration.

 Same config and site access gives 0.2.4.27
 and 0.2.5.12 fits, though eventually it
 works.  Have fallen back to old version
 because 0.2.6.9 fails consistently,
 though in a different manner than the
 bug-trap so far.

 Possibly the site in question is currently
 under DDOS and so the opportunity to reproduce
 may be time-limited to the attack.

 Contact me privately at starlight dot 2015q2
 at binnacle dot cx for the details.
