<pre>Here's a macro to reproduce the issue (just select a few points and click ok on
the two dialogs):
run("Fluorescent Cells (400K)");
setTool("multipoint");
run("Select None");
waitForUser("Select points. Then press 'OK'");
run("Add to Manager");
run("Select None");
c=roiManager("count");
roiManager("select", c-1);
roiManager("Rename", "points1");
makePoint(0, 0);
run("Add to Manager");
run("Select None");
c=roiManager("count");
roiManager("select", c-1);
roiManager("Rename", "single_point");
setTool("multipoint");
run("Select None");
waitForUser("Select more points. Then press 'OK'");
run("Add to Manager");
run("Select None");
c=roiManager("count");
roiManager("select", c-1);
roiManager("Rename", "points2");
roiManager("Save", getDirectory("temp") + File.separator +
"test_rois.zip");
This will throw the exception below (using up-to-date Fiji as well as the Dec
2015 life-line version), tested on Windows and Mac OSX. The behavior is
specific to multi-channel images.
Everything works fine when using the Nov 2014 life-line version of Fiji.
