Bug introduced in 9.0 and fixed in 9.0.1

This is a more of a problem report than a question. When merging the two cells Cell1:

foo
(*foobar*)
bar

and Cell2:

foobar

the line immediately before the comment together with the comment line embark on a journey into another universe, leaving nothing behind than a vicious red box and the farewell greeting

"A RowBox with an invalid first argument was encountered. The first argument to RowBox must be a list."

Can confirm there is no problem with this on OS X with V9.0.1 – m_goldberg Mar 08 '13 at 14:08

I confirm this behavior on PC WinXP Math 9.0.1.0. The same behavior has been recently reported at the MathGroup site http://forums.wolfram.com/mathgroup/ – Alexei Boulbitch Mar 08 '13 at 14:38
I've seen similar behavior before, but can't reproduce it at the moment. I suggest you contact support@wolfram.com. – Sjoerd C. de Vries Mar 08 '13 at 14:50
@Rolf Does that mean this bug was present in v9.0.0? If so I will tag it as such. – Mr.Wizard Mar 08 '13 at 18:10
I cannot reproduce this problem in v9.0.1 on OS X. – Szabolcs Mar 08 '13 at 18:35
@Mr.Wizard See here – Szabolcs Mar 08 '13 at 18:36
@AlexeiBoulbitch Do you mean this It was supposed to be fixed in 9.0.1, are you sure you still see this problem after upgrading? – Szabolcs Mar 08 '13 at 18:40

@Mr.Wizard yes. Button["Fix9", (NotebookWrite[#1, NotebookRead[#1] //. HoldPattern[RowBox[a_, b__]] :> RowBox[{a, b}]] & ) /@ Cells[CellStyle -> "Input"]] is the simplest fix. Or Import["http://www.mertig.com/mykeys.m"] as mentioned in this thread – Rolf Mertig Mar 08 '13 at 23:48

@Szabolcs yes, you are right, I meant that report. And you are right, it does not appear any more. I simply did not use Merge Cells command after having lost information with it once. – Alexei Boulbitch Mar 11 '13 at 08:11
Thanks very much for the helpful comments, I'll upgrade then. – malumno Mar 11 '13 at 12:58
I have the same problem on Mathematica v9.0.0 for Mac OS X! – May 01 '13 at 20:58
I have no such problem with Mathematica 9.0.1 under Windows 7 x64. – Alexey Popkov May 02 '13 at 09:30
