In other words, it appears that Gnus is not processing the .overview file after it reads the problematic non-ascii characters. I would be grateful if a Gnus hacker could look into this, as I cannot usefully read gmane.emacs.help with Gnus from the current trunk. (The problem with the marks was also present in the build for which I posted my OP, but I refrained from mentioning it because I thought the file corruption was the real problem. But now the corruption is gone, but the marks problem remains.) Steve Berman ^ permalink raw reply [flat|nested] 4+ messages in thread

I don't use the agent, so I'm not familiar with it, but IIRC it's no problem to delete the corrupt overview file. Does this help?

I had some .overview files that was bigger than 10M and they slowed down Gnus severely. -- .: Leo :. [ sdl.web AT gmail.com ] .: [ GPG Key: 9283AA3F ] :.

This does not help: after deleting the .overview file from News/agent/nntp/news.gmane.org/gmane/emacs/help (but retaining the corresponding .agentview file), all marked (ticked) articles, as well as all seen but unread articles, are missing from the summary buffer. However, the good news is that bug has apparently been fixed in the mean time: I updated from the trunk today and after opening gmane.emacs.help with Gnus all the marks were intact, and remained so after closing and reopening. This is with the previous 14 MB .overview file reinstated. (I was sent an email on March 19 from the testbed Emacs bugtracker saying that Stefan Monnier had closed the bug, but it didn't give details and I cannot tell from the change logs which change contains the fix (I was away when the email was sent and wasn't able to update until today).)
