error while importing beamer file in lyx 2.1

[Olivier MOREL]

Dear developers,

I’m enable to open all my files that use beamer presentation class.
After spending many time I find out that this problem occurs when an alert text is placed inside a block.
Here is the error I have:

Warning: end of layout not found!
Warning: InsetArgument not found!
Warning: Wrong parent layout!
LyX: \end_deeper: depth is already null [around line 141 of file /tmp/lyx_tmpdir.qEVuYwB26553/Buffer_convertLyXFormatXXXXXX.lyx.LavAmpY26553 current token: '\end_deeper' context: 'InsetText::read']
LyX: Missing \end_inset at this point. [around line 176 of file /tmp/lyx_tmpdir.qEVuYwB26553/Buffer_convertLyXFormatXXXXXX.lyx.LavAmpY26553 current token: '\end_document' context: 'InsetText::read']
Error: Problème de format de document
----------------------------------------
/tmp/lyx_tmpdir.qEVuYwB26553/Buffer_convertLyXFormatXXXXXX.lyx.LavAmpY26553 se termine de façon inattendue, ce qui signifie qu'il est sans doute corrompu.


Thank you again for the very good job you do,

Best regards,

Olivier

Dear JÃŒrgen,
Thanks a lot for your prompt message.
Please find a simplified file that gives the error.

This imports fine with the 2.1.1 development version.

You can actually even fix LyX 2.1.0 quite easily. Just look where the file
lyx_2_1.py is installed on your system and replace that file with this one:

HTH
