	Yup. 

	Hmm. I downloaded the source, and after a quick grep for fopen:

[msoulier@lupus src]$ grep fopen *.c
chan.c:   f = fopen(conf, flags);
chan.c:     perror("fopen");
gnapster.c:   f = fopen(download->fpath, "w");
network.c:      dl->fdesc = fopen(conv_unix(dl->file), "r");
network.c:       dl->fdesc = fopen(dl->resume_path, "a");
network.c:      download->fdesc = fopen(download->resume_path, "a");*/
network.c:       download->fdesc = fopen(download->resume_path, "a");
network.c:      download->fdesc = fopen(conv_unix(download->file), "r");
resume.c:   f = fopen(conf, flags);
resume.c:     perror("fopen");
servers.c:   f = fopen(conf, flags);
servers.c:     perror("fopen");
upload.c:   f = fopen(conf, (status == 2) ? "a" : (status ==
1) ? "w" : "r");
upload.c://      perror("fopen");

	I first suspected servers.c, but...

FILE *open_servers(char *flags) {
   FILE *f;
   char *conf;

   conf = g_strdup_printf("%s/.gnapster/servers", getenv("HOME"));
   
   f = fopen(conf, flags);

   if (!f)
     perror("fopen");

   g_free(conf);
   
   return f;
}

	This looks like it's just looking at $HOME/.gnapster/servers,
which is there, so it's probably fine. 

chan.c is the same kind of thing, opening $HOME/.gnapster/autojoin

upload.c has the perror() call commented out, so if the source agrees with
the binary package, it can't be that.

	Looking in resume.c:

FILE *open_resume(char *flags) {
   FILE *f;
   char *conf;
   
   conf = g_strdup_printf("%s/.gnapster/resume", getenv("HOME"));
   
   f = fopen(conf, flags);
   
   if (!f)
     perror("fopen");
   
   g_free(conf);
   
   return f;
}

	It's looking for $HOME/.gnapster/resume, which I don't have. I'm
not sure what that's for, resuming incomplete downloads maybe?

[msoulier@lupus src]$ grep open_resume *.c
gnapster.c:   f = open_resume("r");
resume.c:   f = open_resume("r");
resume.c:   f = open_resume("w");
resume.c:   f = open_resume("r");
resume.c:   f = open_resume("w");
resume.c:   f = open_resume("r");
resume.c:   f = open_resume("a");
resume.c:   f = open_resume("r");
resume.c:FILE *open_resume(char *flags) {

	Looks like it's called a lot, so perhaps it's being called when it
shouldn't be. It'd be worthwhile to add to the perror messages to
distinguish them to make sure that it's the right one, and then track it
down.
