HI all,<br><br>I am running basex 6.7.1 on Ubuntu 10.10 using the .jar module running on OpenJDK runtime 6b20-1.9.9. I received an NPE in the GUI (message below). I have attached my .xq file for your perusal. Let me know if there is any way to work around this, or if downloading a different build will solve it.<br>

Thanks so much<br><br>Error: Potential bug? Improper use? Your feedback is welcome:<br>Contact: <a href="mailto:basex-talk@mailman.uni-konstanz.de">basex-talk@mailman.uni-konstanz.de</a><br>Version: BaseX 6.7.1<br>Java: Sun Microsystems Inc., 1.6.0_26<br>
