Summary0010331: Plugins : file manager or dialog boxes don't open
DescriptionI can't use some plugins (LV2/VST3/VST2) because dialog boxes don't appears.
For example Decent Sampler, Helm.

Plugins that use their own GUI dialog boxes are not affected, issue is with OS boxes (Mint Cinnamon here)

I have no problem using Carla or Reaper.
It was working before, but I can't remember if there was an update of Ardour or OS.
Steps To ReproduceAdd i.e. Decent Sampler plugin (any version).
Use File... --> Load...
A dialog boxe should open, but nothing happens.
TagsNo tags attached.

This is likely caused by older plugins that launch an external app to do that, which can cause dropouts.

I expect the workaround mentioned https://github.com/sfztools/sfizz-ui/issues/74#issuecomment-1565879638 will work.

The zenity workaround you had given works, but not for every plugins.
i.e. Surge and SurgeXT don't work as expected.

Seems like different plugins need different work-around ?
--> Decent Sampler is OK without work-around in Carla and Reaper, but needs the zenity tricks in Ardour and Bitwig
--> SurgeXT is OK without work-around in Carla, Reaper and Bitwig, but does not work in Ardour anyway, so I assume it doesn't rely on zenity.

In the same way, some plugins can't open external links like web links or pdf manuals.
i.e. Decent Sampler "--> Files... --> My Account... --> Account details" should open a web browser, it works in any other DAW but not in Ardour. The previous workaround is not helpful here.

@x42: that's not the case for decent sampler

DecentSampler 1.22.4 works fine with Ardour 9.4 here. Even the "Account Details" part works just fine too (opens the page in my browser).

@paul do you test with the official binary (which sets a path to libraries we bundle)?

Running from source-tree or distro builds are not affected by this issue.

"Open account details" is often blocked when the plugin links against libcurl (as opposed to dlopen() libcurl at runtime).

The former fails usually since libcurl we bundle isn't the system-wide one used at compile-time (libcurl-gnutls libcurl-openssl, etc).
Recent VST3 SDK does dlopen() and work fine.

@x42: you're right, the binary packages do not work with DecentSampler's attempt to open a page in the browser
