Fedora 27, geany-1.33-1.fc27.x86_64

Steps to repro:

1. Open document multiple spaces between words. 2. From menu choose `Search|Replace` 3. Fill in the replace dialogue: `Search for:` <type in two spaces> `Replace`: <type in single space> Only tick boxes: `use escape sequences`, `close dialogue` 4. Click `In document`

5. Geany is spinning with the following callstack
