--- Comment #4 from Pär Pålhed <[email protected]> ---
I suspect that @Clark does not have the extension “PDF Import for Apache
OpenOffice” installed since a PDF-file would automatically open in Draw,
instead of in Writer, when the extension is installed. Based on this
observation the “choking” behavior should be considered as a bug in AOO and not
in the extension. I draw this conclusion as well from my attempt to replicate
the bug.

I used a 21MB PDF-file trying to opening it in AOO4.1.0, AOO4.1.1 and other
editors like Microsoft Word and Notepad. In both versions of AOO it takes 9-10
minutes to open the file regardless if the extension is installed or not. I can
repeat the “choking” behavior every time with the test file, as well as with
other PDF-files of similar size. Link to the test file:
http://www.nbb.be/DOC/BA/PDF7MB/2010/201061200010_1.PDF (21.492 KB). 

When using Microsoft Word or Notepad the test file opens in seconds. This is
quite a big difference that can give the impression of inadequate functionality
or performance in AOO and thereby risk that users steer away from AAO in favor
of other text editors. This is another context to consider when deciding if to
fix this bug or not.

A dialog box “ASCI Filter Options” is displayed by AOO when the file extension
is not recognized by the Open/Import function, i.e. no supporting extension
file is installed. This is described in the documentation as an attempt to open
the file content using the defined filter options. In my initial replication
efforts I used the default settings – “Character set” is set to “Western Europe
(Windows-1252/WinLatin1)”, “Default fonts” to “Times New Roman”, “Language” to
“English (USA)” and “Paragraph break” to “CR & LF”. As a user I would expect
information to be displayed explaining that the file extension is not supported
and how the user's choice of file type affects the files displayed in the file
chooser as well as what filters that may be used to open or import the file. 

Furthermore, by changing “Character set” from default value to “Unicode” I
could make AOO4.1.x crash, even when using very small PDF-files (except for a
blank file). I could not replicate the crash by changing “Character set” to any
other values, or values for any of the other available filter options in this
dialog box. However, as a user I would expect more graceful handling when
changing options, as in general.
