Some notifications are blank/empty regarding the tweet content

[Contribucious]

I think that I only have this problem on XFCE, which don't use the notify-OSD daemon but xfce4-notifyd instead (better looking, more customizable —and by built-in settings in addition— by the way).

Shortly: I sometimes have a notification with "New tweet from XXXX" title but with no tweet content.
And if I check in the Birdie window, I see this tweet correctly with the tweet content.

I don't have looked more to see if we can found a common pattern between these tweets that appeared empty >in the notification< through. But perhaps there is none. I think it was all tweets with image, but not sure at all. Perhaps it's again a parsing problem (regarding notifications only therefore, which don't make much sense, as it's global the parsing I think) that prevents completely the tweet content to be shown there. I don't know…

[EDIT1] Just seen this problem again in a notification and no image link in this tweet. Just few words with a normal link (here to twitter.com/search/realtime?q=XXXX&src=typd). The only "special" things I see is that the link contains, in the XXXX part, some % characters.
%20 for space encoding in the URL, and some others like %9C %C3 (among others so).

[EDIT2] And now, a new one again. This time, no very special characters (just "?"). Strange!
Just a small text + a classic URL: http://xxxx/xxx.html?utm_source=xxx&...
But very long the URL through... (and as t.co is not used for notifications…). So, maybe it's because of the length of that URL that the notification content was not shown, but I can however send a VERY long notification from my terminal (using notify-send) and the xfce4-notifyd daemon will show me this one without problem, i.e. I'll see the content sent. And in fact, even with the SAME TWEET CONTENT (copy/pasted to my terminal), I can send it using notify-send and see it without problem. So, it's very strange… but happens often when I'm on XFCE anyway…
