I kept getting the following stack trace when attempting to submit a new bug against a product that contained a space. (eg. Linux Tools). java.lang.IllegalArgumentException: Invalid uri '/bugs/enter_bug.cgi?product=Linux Tools': Invalid query at org.apache.commons.httpclient.HttpMethodBase.<init>(Unknown Source) at org.apache.commons.httpclient.methods.GetMethod.<init>(Unknown Source) at org.eclipse.mylyn.internal.bugzilla.core.GzipGetMethod.<init>(GzipGetMethod.java:45) at org.eclipse.mylyn.internal.bugzilla.core.BugzillaClient.getTokenInternal(BugzillaClient.java:1245) at org.eclipse.mylyn.internal.bugzilla.core.BugzillaClient.postTaskDataInternal(BugzillaClient.java:1313) at org.eclipse.mylyn.internal.bugzilla.core.BugzillaClient.postTaskData(BugzillaClient.java:1204) at org.eclipse.mylyn.internal.bugzilla.core.BugzillaTaskDataHandler.postTaskData(BugzillaTaskDataHandler.java:415) at org.eclipse.mylyn.internal.tasks.core.sync.SubmitTaskJob.run(SubmitTaskJob.java:101) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54) After looking at upstream for solutions, I found this : https://bugs.eclipse.org/bugs/show_bug.cgi?format=multiple&id=382194 It would seem to be fixed in a snapshot build of 3.8.
It seems that this is fixed in Mylyn Tasks 3.8.1 (https://bugs.eclipse.org/bugs/buglist.cgi?query_format=advanced;product=Mylyn%20Tasks;target_milestone=3.8.1)
