by roughly reading amule source i can see quit is set to true if amuleweb starts with --amule-config-file to avoid writing to fd 1, but it still write to fd 1 as you can see from my strace loghope you have better idea than i do

Please run amuleweb with gdb to get a backtrace (it has to have debug info).

it is reproducable if file name is not ascii like the following url
ed2k://|file|%5B%E5%90%8D%E4%BE%A6%E6%8E%A2%E6%9F%AF%E5%8D%97.%E5%89%A7%E5%9C%BA%E7%89%88%E7%AC%AC%E5%8D%81%E5%9B%9B%E5%BC%B9.%E5%A4%A9%E7%A9%BA%E7%9A%84%E9%81%87%E9%9A%BE%E8%88%B9%5D.%5BHYSUB%5Dxxxxxxxxxxxxxxxxxxxxxx%5BDVD-RMVB%5D%5BGB_RV10%5D%5B856X480%5D.rmvb|492999999|000000000000000000000000000000|h=km6ylogseygmefpjoi4ibt7pmhnoobew|/ [^]
i found a way to workaround some url by using amulecmd instead, but the above url is refused by amulecmd
 > Request failed with the following error: Invalid link or already on list.
after i remove the non-ascii part of filename from the url, it works, either in amulecmd or amuleweb

what do you wan't from gdb? it's a normal exit and what backtrace should i print? break on Show function and cath the message "Template not found, reverting t"? i'll have to recompile amule but you can try the above link

btw, the non-ascii part of filename is UTF-8 encoding, and then URL encoded

so we get 2 problem.
1. handle utf-8 filenames (or because there's no locale files/support on openwrt?)
2. never ever write to fd 1 when amuleweb is started by amuled

write(1, "Template not found, reverting t"..., 43) = -1 EPIPE (Broken pipe)
--- SIGPIPE (Broken pipe) @ 0 (0) ---
exit_group(-1) = ?

i have no idea yet on why it's triggered, the logic and the m_KeepQuiet variable is correct

something going wrong inside unicode2char i guess, non-ascii character(s) is in i->first or i->second (in typeof wxString) and it's not gonna convert to std::string with current locale

be aware that i'm using openwrt, i'm not sure how to add locale to it or does it have a locale support

the openwrt is built with eglibc 2.12 (and also tested with glibc 2.7)
target-i386_eglibc-2.11
target-i386_glibc-2.7

the ed2k url is always UTF-8 encoded. i strongly suggest amule to use UTF-8 as encoding (before it's urlencoded) between ExternalConnectors (amuleweb / amulecmd) and amuled

the ExternalConnectors should take care of user input encoding if necessary on the client side
and amuled take care of its own filename encoding at the server side

when locale is not supported, fall back to UTF-8 encoding

The m_KeepQuiet logic was surely flawed. Please try if 10486 fixes your problem.

I pasted your link into amuleweb, and it made no problem. The Chinese chars showed up correctly in amule (though not in amuleweb, but that's a different story).

Oh, and please never post real ed2k links here. Make a bogus link that shows the problem instead.
