Gajim UI unresponsive during history search
Gajim v1.4.0-dev1+6a3fda13 on Debian Testing.
Press C-h to open history for a busy MUC -> search for something. Search may take a long time and Gajim's UI becomes unresponsive.
Possible solutions may be to make search asynchronous, and to search lazily. (only search enough to fill the visible height of the search result window, and search further on scrolling)
