[Tex/LaTex] Error when using \cite with page number in short caption of table


when using the \cite command with a page number in the short caption of a table or figure along with the command \listoftables, I keep getting the following set of error messages:

./Test_Bibtex.lot:3: Argument of \blx@citeargs@i has an extra }.
<inserted text> 
l.3 ...{\ignorespaces Short caption (\cite [5}}{1}

Runaway argument?
./Test_Bibtex.lot:3: Paragraph ended before \blx@citeargs@i was complete.
<to be read again> 
l.3 ...{\ignorespaces Short caption (\cite [5}}{1}

Quite obviously, there seems to be problem that has to do with the parsing of the page number in the .lot file.

Here you can see a MWE where the first \caption command creates the error as it contains a page number, while the second (commented) one works alright:


    Address = {New York},
    Author = {Geertz, Clifford},
    Date-Added = {2013-08-09 17:17:10 +0000},
    Date-Modified = {2013-08-09 17:18:06 +0000},
    Publisher = {Basic Books},
    Title = {The Interpretation of Cultures. Selected essays},
    Year = {1973}}

\usepackage[style=authoryear, useprefix=true, language=english]{biblatex}


  \caption[Short caption (\cite[5]{Geertz:1973})]{A longish caption of the table, inspired by \textcite[5]{Geertz:1973}} % creates the problem, due to the page number
  %\caption[Short caption (\cite{Geertz:1973})]{A longish caption of the table, inspired by \textcite{Geertz:1973}} % works, as there is no page number


Any suggestions on how to get this to work?

Thank you in advance!

When using a command with optional arguments in the optional argument of another command one must protect the inner ] by putting {...} around the inner command so that TeX doesn't think it ends the outer argument (TeX doesn't check the nesting of such [..] braces as it would do for {..})

  \caption[Short caption ({\cite[5]{Geertz:1973}})]{A longish caption ...}
