The same message I can see in the Apache log file. There is also
following warning:
Is it Ikiwiki bug or my attachment plugin is misconfigured? --[[Paweł|ptecza]]
-> Joey, please fix the colon in page name of my report. Ikiwiki sets
-> "attachment:\_failed\_to\_get\_filehandle/" URL on "Bugs" page and
-> the report is not clickable in my Epiphany browser:
-
-> Firefox doesn't know how to open this address, because the protocol
-> (attachment) isn't associated with any program.
-
-> I can only edit it :) Bad handling ':' character by Ikiwiki is probably
-> its another bug.
-> --[[Paweł|ptecza]]

+> debian stable/ubuntu hardy. Trying to figure it out --[[Joey]]
