Confirming this bug.

Ubuntu 8.10 Beta
yelp 2.24.0-0ubuntu1

Only affect LANG=pl_PL.UTF-8
When I try to search "guest" or "network", program always crash. Everything is OK when I search for example "ubuntu".
On LANG=en_US.UTF-8 everything works fine.

Hi all
I noticed that when search the word "server" (without " character ) with yelp application this crash. I have reproduced this problem up two different computer with Ubuntu 8.10.

In the log file I noticed this string problem:
yelp[6690]: segfault at 0 ip b741e2c3 sp bff0551c error 4 in libc-2.8.90.so[b73a7000+158000]

I have solved this bug.
The error it is in function "search_clean_snippet" when search single word in this while chicle:

 while ((str = strstr (result, (iteration[i])))) {
     gboolean breaking = FALSE;
     gint i;
     str = strstr (str, (iteration[i]));
  if (!str) {
      breaking = TRUE;
      break;
  }
     }

first of all I have changed the variable i with k, and I have add the control in end iterator, that was the problem.

 while ((str = strstr (result, (iteration[i])))) {
     gboolean breaking = FALSE;
     gint k;
     for (k=0; k< count; k++) {
  str++;
  if(iteration[k] ==NULL){
      breaking = TRUE;
      break;
  }
  str = strstr (str, (iteration[k]));
  if (!str) {
      breaking = TRUE;
      break;
  }
     }
