Ok, I could track it down to a NullPointerException in
WorkbenchPage.showPart():<br>
<br>
private MPart showPart(int mode, MPart part) {<br>
switch (mode) {<br>
case VIEW_ACTIVATE:<br>
...<br>
case VIEW_VISIBLE:<br>
MPart activePart = partService.getActivePart();<br>
if (activePart == null) {<br>
...<br>
} else {<br>
part = ((PartServiceImpl)
partService).addPart(part);<br>
MPlaceholder activePlaceholder =
activePart.getCurSharedRef();<br>
MUIElement activePartParent = activePlaceholder ==
null ? activePart<br>
.getParent() :
activePlaceholder.getParent();<br>
partService.showPart(part, PartState.CREATE);<br>
if (<font color="#ff0000"><b>part.getCurSharedRef()</b></font>.getParent()
!= activePartParent) {<br>
partService.bringToTop(part);<br>
}<br>
}<br>
break;<br>
<br>
The part is the History view and its getCurSharedRef() method
returns null:<br>
<br>
java.lang.NullPointerException<br>

The org.eclipse.ui.workbench plugin has the version
3.107.0.v20150127-1326. It's strange that the problem does not
happen in another IDE with the identical workbench version. The two
IDE differ in their EGit versions, though:<br>
<br>
EGit 3.7.0.201502040827 (Good IDE)<br>
EGit 3.7.0.201502031740-rc1 (Bad IDE)<br>
<br>
