BEAUti incorrectly generate the xml file after unlinking the trees

[carlopacioni]

I have a nexus file with multiple partitions in nexus format. I have imported it, linked the substitution, clock and trees. Then in the prior tab, I have selected the EBSP prior (the idea being that so I don't have to select this prior for each of the multiple partitions I have - the data are short reads used to generate genomewide SNP, so lots of partitions!) and, returned to the first tab, I have unlinked the trees. As expected the EBSP tree prior gets populated for all partitions, but the XML is incorrectly generated (I get the error: "Fatal exception: 204"). I believe that the error stems from the fact that BEAUti progressively insert the previous treeIntervals in the EBS block (see below how treeIntervals.t:64668207 is inserted in the last block). This does not happen (and the XML runs normally) if I don't link the partitions before selecting the tree prior, but I manually select the tree prior for each partition.
